Why can’t I connect to my EnterpriseDB deployment? 

If you encounter errors when connecting to your IBM Cloud® Databases for EnterpriseDB deployment, review these common causes and resolutions.

  What’s happening 

You receive an error message or fail to connect to a Databases for EnterpriseDB deployment. If reviewing application logs, you might see errors that mention intermittent connection timeouts or unable to connect.

Review the following information to troubleshoot and resolve common connectivity problems:



*  An unsecured connection is a common cause of connectivity errors. All Databases for EnterpriseDB connections use TLS/SSL encryption; Databases for EnterpriseDB rejects unsecured connections. To avoid errors, make sure you configured a secure connection. Refer to [Getting Started](https://cloud.ibm.com/docs/databases-for-enterprisedb?topic=databases-for-enterprisedb-getting-started) for an example of a secure connection.
*  If you are using a private endpoint, make sure that you specify connection strings that contain the private endpoint (see [Credentials for Private Endpoints](https://cloud.ibm.com/docs/databases-for-enterprisedb?topic=cloud-databases-service-endpointscredentials-for-private-endpoints)) and that you followed the steps in [Connecting through Private Endpoints](https://cloud.ibm.com/docs/databases-for-enterprisedb?topic=cloud-databases-service-endpointsprivate-endpoint-connections).
*  If your application log captures a short connection interruption, that behavior is expected as a normal part of operations for this managed service. You want to design your applications to retry connections when errors are caused by a temporary loss in connectivity to your deployment or to IBM Cloud. However, if you experience several minutes of connection interruption check the Cloud Status for the service. For more information, see [Application-level High-Availability](https://cloud.ibm.com/docs/databases-for-enterprisedb?topic=databases-for-enterprisedb-high-availabilityapplication-level-high-availability).
You received an activity ID when you successfully completed the action in the Schematics workspace.



5. Run the Python script by using python3 <python-file-name> to retrieve the logs for an action for your Schematics workspace in the IBM Cloud.
6. You get an action ID, name, and action status, such as COMPLETED or FAILED, in response when it is determined whether the parameters passed as part of the request are valid. You should be able to retrieve the logs for an action for a specific Schematics workspace. If you don’t get a successful response, the error response contains the errors that you need to resolve. Resolve those errors and run the script until you are able to get a valid response and can retrieve the logs.

 Why is the internet disconnected? 

If your internet is disconnected, it might be caused by one of the following reasons.



* [Internet is blocked by firewall or gateway](https://cloud.ibm.com/docs/virtual-servers?topic=virtual-servers-troubleshooting-virtual-serverinternet-blocked-by-firewall-or-gateway)
* [Public gateway IP configuration](https://cloud.ibm.com/docs/virtual-servers?topic=virtual-servers-troubleshooting-virtual-serverpublic-gateway-ip-configuration)
* [No ping from DNS servers](https://cloud.ibm.com/docs/virtual-servers?topic=virtual-servers-troubleshooting-virtual-serverping-DNS-servers)





 Internet is blocked by firewall or gateway 

If you can't access the internet, your internet access might be blocked by your firewall or gateway (Vyatta, AT&T, Juniper, Fortigate).





 Public gateway IP isn't configured for the network card 

If firewall is not an issue, check whether the public gateway IP is configured for the public network card and try pinging the public gateway. For more help, contact [support](https://cloud.ibm.com/docs/virtual-servers?topic=virtual-servers-gettinghelp).





 No ping from DNS servers 

Check whether you can ping IBM DNS servers (10.0.80.11, 10.0.80.12), if you configured DNS servers for the public network card.

If you have Linux servers, add the following entries in the /etc/resolv.conf file:

nameserver 10.0.80.11 and nameserver 10.0.80.12







 Why does the portal show that my server is disconnected even though it's running? 

If your portal shows that the server is disconnected, but the server is running, it might be caused by one of the following reasons.
Enter the [ibmcloud user-policy-create](https://cloud.ibm.com/docs/cli?topic=cli-ibmcloud_commands_iamibmcloud_iam_user_policy_create) command to assign access to all resources in a resource group or to just one service within a resource group. This example gives name@example.comOperator role for resource group with ID dda27e49d2a1efca58083a01dfde18f6:

ibmcloud iam user-policy-create name@example.com --roles Operator --resource-type resource-group --resource dda27e49d2a1efca58083a01dfde18f6

Enter the [ibmcloud iam service-policy-create](https://cloud.ibm.com/docs/cli?topic=cli-ibmcloud_commands_iamibmcloud_iam_service_policy_create) command to assign access to all resources in a resource group or to just one service within a resource group. This example gives service testAdministrator role for resource group called sample-resource-group:

ibmcloud iam service-policy-create test --roles Administrator --resource-group-name sample-resource-group





 Assigning access to manage a resource group by using the CLI 

You can assign access to view or manage a resource group without assigning service access.

As an administrator, you might want to create an access group with the Viewer role on all resource groups. This way, when you assign access to service resources you don’t have to create additional policies for viewing resource groups. The Viewer role on a resource group is required for a user to create a service instance in that resource group.

The following example creates a policy for Viewer of a specific resource group:

iam user-policy-create name@example.com --roles Viewer --resource-type resource-group --resource fec6c95e6a0a44c5bcca138bfe5a1f9e

The following example creates a policy for Viewer of all resource groups in the account.

If your server has pending Windows updates, install the latest updates, restart the server, and try to access RDP.







 Why can't I connect to a server through the public IP? 

If you can't connect to a server through the public IP, it might be caused by one of the following reasons.



* Public traffic is blocked by your firewall or gateway (Vyatta, AT&T, Juniper, FortiGate).
* If the firewall isn't an issue, check whether the public gateway IP is configured for the public network card and try pinging the public gateway. For more help, contact [support](https://cloud.ibm.com/docs/virtual-servers?topic=virtual-servers-gettinghelp).
* Check whether you can ping IBM Cloud® DNS servers (10.0.80.11, 10.0.80.12), if that they are configured in the public network card.







 Why is the internet disconnected? 

If your internet is disconnected, it might be caused by one of the following reasons.



* [Internet is blocked by firewall or gateway](https://cloud.ibm.com/docs/bare-metal?topic=bare-metal-troubleshooting-bare-metalbm-internet-blocked-by-firewall-or-gateway).
* [Public gateway IP configuration](https://cloud.ibm.com/docs/bare-metal?topic=bare-metal-troubleshooting-bare-metalbm-public-gateway-ip-configuration).
* [No ping from DNS servers](https://cloud.ibm.com/docs/bare-metal?topic=bare-metal-troubleshooting-bare-metalbm-ping-DNS-servers).





 Internet is blocked by firewall or gateway 

If you can't access the internet, your internet access might be blocked by your firewall or gateway (Vyatta, AT&T, Juniper, FortiGate).





 Public gateway IP isn't configured for the network card 

If the firewall is not an issue, check whether the public gateway IP is configured for the public network card and try pinging the public gateway.
If you don’t want to see the warning, you can specify the --platform linux/amd64 option on your docker run command.
6. Verify that the container platform can pull the image. The image is located in the IBM Container Registry at icr.io/ibm/satellite-connector/satellite-connector-agent:<version>. Make sure you have specified the image correctly. The machine running the agent has network access to icr.io, and that you have logged in to the IBM Container Registry. For more information, see [Pulling the agent image](https://cloud.ibm.com/docs/satellite?topic=satellite-run-agent-locallypull-agent-image).



Note to Docker Swarm users: If you see the following error about “No such image”:

icr.io/ibm/satellite-connector/satellite-connector-agent:v1.0.4 swarm-worker1 Shutdown Rejected 5 minutes ago "No such image: icr.io/ibm/sat…"

This means Docker Swarm was unable to pull the image. It is likely due to invalid IBM Container Registry credentials. To resolve this issue:



1. Remove the service.
2. Log in to the IBM Container Registry.
3. Restart the stack.







 Tunnel is established - Agent container is listed in the Active Agents tab on the console 

If your agent container is listed in the Active Agents tab on the console, follow these debugging steps:



1. Go to your Connector instance and open the Logging Dashboard. This automatically filters the logging output for your Connector ID.
2. Review the error messages.

After the tunnel is established, any errors will be located in both the IBM Log Analysis instance and in the agent’s container platform logs. Most errors will now be those trying to access an endpoint from within IBM Cloud to an application running on-prem over the tunnel. When accessing an endpoint, at the start of the connection a flowlog entry is written to the logging instance. For example:
It's recommended to cache the access token.





 Step 2: Validating user permissions 

Now that you have the access token, and you authenticated your user, you need to validate that they have the permission to access the dashboard of a service instance. Accessing the dashboard of a service instance is the only action that can be used to validate user authorization.

You must decode the information that is included in the user's access token. After the token is decoded, you can use that information to call IAM to check whether the user is authorized to access the service dashboard.



 Decoding the user's access token 

Decode the user's access token, which was returned during step 3. The access token is a JSON Web Token (JWT) that can be decoded by using any JWT-compliant library.

After the token is decoded, you can view the following information:

Known restrictions 

If you find a problem while you use Event Streams, review the following known restrictions and workarounds.



 Java Kafka calls don’t failover if a Kafka bootstrap server fails 



 Problem 

The Java™ Virtual Machine (JVM) caches DNS lookups. When the JVM resolves an IP address for a hostname, it caches the IP address for a specified period, which is known as the time to live (TTL). Some Java configurations set the JVM TTL so that it never refreshes a hostname’s IP address until the JVM is restarted. An example configuration is one that has a security manager.





 Workaround 

Because Event Streams uses Kafka bootstrap server URLs with multiple IP addresses for high availability, not all the broker IP addresses are known to the Kafka client, which prevents failover to a working broker. In these cases, a failover requires a requery of the IP addresses for the broker URLs to get a working IP address. You are recommended to configure your JVM with a TTL value of 30 to 60 seconds. This value ensures that if a bootstrap server’s IP address has issues, the Kafka client is able to look up and use a new IP address by querying the DNS.

See the following example from the java.security file:

 The Java-level namelookup cache policy for successful lookups:

 any negative value: caching forever
 any positive value: the number of seconds to cache an address for
 zero: do not cache

 default value is forever (FOREVER). For security reasons, this
 caching is made forever when a security manager is set. When a security
 manager is not set, the default behavior in this implementation
 is to cache for 30 seconds.

 NOTE: setting this to anything other than the default value can have
 serious security implications. Do not set it unless
 you are sure you are not exposed to DNS spoofing attack.

networkaddress.cache.ttl=-1
