Question: How can I troubleshoot 410 GoneException errors with Amazon API Gateway WebSocket APIs?

I get a "410 GoneException" error when trying to post a message to my Amazon API Gateway WebSocket API similar to the following:..."errorMessage": "GoneException: 410"...How do I troubleshoot this?Short descriptionYou might receive the "410 GoneException" error if:A message was posted to the WebSocket API before the connection was established.The connection has been terminated, or the connection doesn't exist anymore.The client disconnected and then tried to reconnect using the same connectionId.Note: For WebSocket APIs, the connectionId is required to send a callback response from the backend.

ResolutionTo troubleshoot WebSocket API errors, turn on Amazon CloudWatch Logs.Note: For Log level, choose INFO to generate execution logs for all requests.Execution logs contain information that you can use to identify and troubleshoot most API errors. For example:The requests that your API receivesThe integration backend responses from your APIThe response provided by AWS Lambda authorizersThe requestId for AWS integration endpointsFor more information about each type of logging, see CloudWatch log formats for API Gateway.Before posting messages to WebSocket APIs, make sure that your connection is established by calling the getConnection operation using the AWS SDK ApiGatewayManagementApi.Avoid making the postToConnection request from the Lambda function integrated with your $connect route. For example, if you want to post a message after the client connection is established, do the following:Create a child Lambda function that's asynchronously invoked by the parent function.On initiation of a new connection, the $connect route is invoked and the parent function invokes the child function passing the connectionId.The Lambda child function receives the connectionId and calls the getConnection operation to verify that the connection is valid. Then, the message is sent using the postToConnection method.

Question: How do I delete or terminate Amazon RDS resources?

I want to reduce or eliminate the Amazon Relational Database Service (Amazon RDS) resources that are associated with my AWS account.

ResolutionThere are three main resources in Amazon RDS that incur billing charges: DB instances, DB clusters, and snapshots. To get a list of these resources that are active on your account, run the following commands in the AWS Command Line Interface (AWS CLI):aws rds describe-db-instancesaws rds describe-db-clustersaws rds describe-db-snapshotsaws rds describe-db-cluster-snapshotsTo stop all Amazon RDS related charges for an account, do the following in all AWS Regions:Delete all RDS DB instances.Delete Amazon Aurora clusters, if you have any.Delete all snapshots.For RDS DB instances and Aurora DB clusters, make sure that the delete protection feature is turned off. Otherwise, you can't delete these resources. For more information, see How can I troubleshoot an error that I received when deleting an Amazon Aurora cluster?Automated Backups can also incur charges. Unlike manual snapshots that must be deleted manually, automated backups persist only for the specified retention period. This retention period applies when you delete the DB instance. To delete your backups manually, see Deleting retained automated backups. Note that after backups are deleted, you can't recover their data.If you purchased reserved DB instances, then those instances are billed according to contract that you agreed to when you purchased the instance.If you delete the Amazon RDS resources mentioned earlier but you still see charges on your monthly bill, review your AWS Billing console dashboard.

Question: What happens during an EC2 scheduled maintenance event and what preventative actions can I take?

My Amazon Elastic Compute Cloud (Amazon EC2) instance has a maintenance event scheduled and I want to better understand how it affects me.

Short descriptionAmazon EC2 maintenance is often a live-update to minimize customer impact. Because a live-update isn't always possible, a scheduled maintenance event can sometimes occur.A scheduled maintenance event might require your instance to undergo one of the following:Stop or retireRebootLose network connectivity or powerThe instance actions that your maintenance event requires depends on the instance configuration and the type of maintenance that is being performed.

ResolutionDepending on your situation, you can perform one of the following actions before the specified maintenance window:Reschedule the maintenance eventIf your instance must undergo a reboot, then reschedule the event so that your instance reboots at a date and time that suits you. For more information, see Reschedule a scheduled event.Stop and start your instanceIf your instance has an Amazon Elastic Block Store (Amazon EBS) volume as its root device, then complete maintenance by stopping and starting your instance. A stop and start migrates your instance to a new underlying host.The stop and start changes the status of the scheduled maintenance event to Completed. The actions, when completed, can take up to an hour to be reflected in the status change. For more information, see View scheduled events.Important: Stopping and restarting the instance changes the public IP address of your instance. It's a best practice to use an Elastic IP address instead of a public IP address when routing external traffic to your instance.Automatically recover an instanceYou can create an Amazon CloudWatch alarm that monitors an Amazon EC2 instance. You can configure the alarm to automatically recover the instance if the instance is impaired due to an underlying hardware failure. For more information, see Recover your instance.Create an instance store-backed AMIIf the instance is based on an instance store or an ephemeral root volume, then you might face issues if your instance is scheduled to terminate rather than reboot. You must create an instance store-backed AMI, then migrate your data and relaunch the instance.Let the maintenance event continue as scheduledIf the maintenance schedule is network connectivity, power maintenance, or a required reboot, then you can let the maintenance event continue as scheduled without intervention.

Question: Why can't I join an organization in AWS Organizations?

I can't join a particular organization in AWS Organizations. Why is that, and what can I do to fix it?ResolutionHere are some reasons why you might not be able to join an organization:You're already a member account of a different organization. Remove your account from its current organization, and then try again.You're already the management account of a different organization. If you try to link your account to a management account, but you've already created an organization with your account as the management account, then you receive an error. To join an organization as a member account, you must convert your account from a management account to a standalone account. For more information, see remove all member accounts from your organization and delete the organization.Your account isn't verified and activated. Be sure that you fully complete the account sign-up and activation process. Some services can take up to 48 hours to fully activate after the account sign-up process is completed. For more information, see How do I create and activate a new AWS account?You didn't accept the invitation to the organization, or the organization didn't send you one. Be sure to accept the invitation in the Organizations console. You might need to wait a few minutes before the Organizations console or Billing and Cost Management console reflect that you're a member of the organization. If you didn't receive an invitation, ask the administrator of the management account to send you a new invitation.Your account has a different seller of record or AWS partition than the management account of the organization that you're trying to join.

Question: I accidentally disabled network connectivity to my Amazon EC2 Windows instance. How do I fix it?

I accidentally disabled network connectivity in Windows. Now, I’ve lost connection to my Amazon Elastic Compute Cloud (Amazon EC2) Windows instance. How can I fix this?ResolutionMethod 1: Use the EC2 Serial ConsoleIf you enabled  EC2 Serial Console for Windows, you can use it to troubleshoot supported Nitro-based instance types. The serial console helps you troubleshoot boot issues, network configuration, and SSH configuration issues. The serial console connects to your instance without the need for a working network connection. You can access the serial console using the Amazon EC2 console or the AWS Command Line Interface (AWS CLI).Before using the serial console, grant access to it at the account level. Then create AWS Identity and Access Management (IAM) policies granting access to your IAM users. Also, every instance using the serial console must include at least one password-based user. If your instance is unreachable and you haven’t configured access to the serial console, then follow the instructions in Method 2: Create a temporary elastic network interface. For information on configuring the EC2 Serial Console for Linux, see Configure access to the EC2 Serial Console.Method 2: Create a temporary elastic network interfaceYou can create a temporary elastic network interface, and attach the network interface to the Amazon EC2 Windows instance. Then, you can temporarily connect to the instance and fix the issue.Open the Amazon EC2 console, and then choose Instances from the navigation pane.Select your instance. From the Description tab, make a note of the Subnet ID.Create a new network interface in the same subnet as the instance.Important: Be sure to select a security group that allows incoming Remote Desktop Protocol (RDP) traffic from your IP address.Attach the new network interface to the instance.Note: The network interface might take a few minutes to come online. If you connect to the instance using RDP, associate an Elastic IP address with the network interface.Using the new network interface, connect to the instance using RDP.Change the network connection settings in Windows to use DHCP. Or, specify the correct private IP address settings. For instructions, see Configure a secondary private IPv4 address for your Windows instance.Detach the temporary network interface.Note: If you associated an Elastic IP address with the network interface but no longer need the Elastic IP address, release the Elastic IP address.

Question: How can I reduce the latency of HLS delivery in MediaLive?

I'm noticing a delay in the HLS delivery of my AWS Elemental MediaLive channel. How can I fix this?ResolutionDelays in HLS delivery can be due to various factors, such as encoding and decoding, network conditions, and player buffers. For more information on measuring latency and optimizing your configuration, see How to Compete with Broadcast Latency Using Current Adaptive Bitrate Technologies.One way to potentially reduce latency is to shorten the segment length of the HLS group:Important: Shortening segment length can impact video quality and increase the chance of player-buffering events. Before you proceed, consider the impact for your use case.Open the MediaLive console.From the navigation pane, choose Channels. Then, choose the channel that you want to modify.Choose Actions, and then choose Edit.Choose the HLS output group that you want to modify.Choose Manifest and Segments.For Segment Length, change the value to 1.Then, choose one output within the HLS group.Choose GOP Structure.For GOP Size Units, select SECONDS.For GOP Size, enter 1 to match the segment length of one second.Repeat steps 7 through 10 for all outputs in the HLS group.After you update the outputs, choose Update Channel.
Question: Why is my AWS Glue crawler not adding new partitions to the table?

My AWS Glue crawler doesn't add new partitions to the table.

Short descriptionWhen the crawler scans the source data files under a new partition, the crawler compares the following attributes of the source files with those of the existing table:File formatCompression typeSchemaStructure of Amazon Simple Storage Service (Amazon S3) partitionsIf any of these attributes of the partition differ from attributes of the table, then the partition is skipped and not added to the metadata. A difference in the name, sequence, or number of partitions in the Amazon S3 path is considered as a change in the partition schema or structure.

ResolutionTroubleshoot the issueCheck the crawler logs to identify the issue:Open the AWS Glue console.In the navigation pane, choose Crawlers.Select the crawler, and then choose the Logs link to view the logs on the CloudWatch console.Review the logs to check if the crawler skipped the new partition.For example, suppose that the log includes entries look similar to the following:Folder partition keys do not match table partition keys, skipped folder: doc-example-bucket/doc-example-path/doc-example-table/year=2021/month=01/sday=05/This entry suggests that the partition structure for the Amazon S3 location doesn't match the partition keys defined for the table. This might happen when the partition structure isn't consistent across the table source location.If the AWS Glue crawler creates multiple tables, then the log entries look similar to the following:INFO : Created table doc-example-table in database doxtest_dbIf you see similar logs, then compare the schema and partition structure of the location of these tables with those of the original table.Resolve the issueBased on the information from the CloudWatch logs, consider one or more of the following solution options:If the issue is caused by inconsistent partition structure, then make the structure consistent by renaming the S3 path manually or programmatically.If the partition is skipped due to mismatch in file format, compression format, or schema, and the data isn't required to be included in the intended table, then consider the following:Use an exclude pattern to skip any unwanted files.Move the unwanted file to a different location.If your data has different schemas in some input files and similar schemas in other input files, then combine compatible schemas when you create the crawler. On the Configure the crawler's output page, under Grouping behavior for S3 data (optional), select Create a single schema for each S3 path. When this setting is turned on and the data is compatible, then the crawler ignores the similarity of specific schemas when evaluating S3 objects in the specified include path. For more information, see How to create a single schema for each Amazon S3 include path.If the crawler is creating multiple tables, then see How can I prevent the AWS Glue crawler from creating multiple tables?
Question: Why am I getting a 200 response with "InternalError" or "SlowDown" for copy requests to my Amazon S3 bucket?

I'm trying to perform a copy operation on my Amazon Simple Storage Service (Amazon S3) bucket. However, Amazon S3 returns a 200 response with "InternalError" or "SlowDown," similar to the following:"AmazonS3Exception: We encountered an internal error. Please try again. (Service: Amazon S3; Status Code: 200; Error Code: InternalError; Request ID: 0EXAMPLE9AAEB265)"How can I avoid this error?ResolutionIf you get a 200 response with "InternalError" or "SlowDown" embedded in the response, then an internal error occurred after the copy operation started. You might see 200 responses with these errors when you run CopyObject, UploadPartCopy, or CompleteMultipartUpload API operations.Note: Because a 200 response can contain an error, consider designing your application to parse the contents of the response body to look for any errors. Then, the application can handle the success or error within the response appropriately.A 200 response with "InternalError" or "SlowDown" is similar to a 5xx error. To troubleshoot or avoid a 200 response with "InternalError or "SlowDown", consider the following:Enable a retry mechanism in the application that's sending requests to Amazon S3.Configure your application to gradually increase request rates.

Question: How do I troubleshoot insufficient capacity error when launching my Amazon SageMaker resources?

I'm getting the Insufficient Capacity error when I'm trying to launch one of the following Amazon SageMaker resources:Training jobBatch transform jobEndpointNotebook instanceSageMaker Studio App

ResolutionThis error occurs when AWS doesn't have enough available on-demand capacity for an Amazon Elastic Compute Cloud (Amazon EC2) instance type within a specific Region or Availability Zone to complete your request. Note that capacity isn't static and varies depending on the time of day and workloads in a particular Region or Availability Zone. This error doesn't result from resource limits that are applied to your account. Because capacity issues are transient, be sure to retry your request when you get these errors.If you need the instance immediately, do the following:Switch to a different instance type. Switch to a different instance size in the same family, or use a different instance family based on your workload. A different instance type might have more capacity.Launch the resource in a different Region. Be sure to verify the SageMaker instance types that are available in each Region.If your request can be delayed, try at a later time to check whether your desired instance is available.Based on the SageMaker resource that you're trying to launch, you can also try the following approaches:If you're launching the SageMaker Studio App, it's a best practice to launch the SageMaker Studio domain with subnets that cover wider Availability Zones. Configuring the resource with subnets that span out in multiple Availability Zones minimizes the possibility of experiencing capacity issues.If you're launching a notebook instance or training job, consider launching the instance with the same instance type while specifying different subnets in different Availability Zones.
