# Troubleshooting Amazon S3 Connector 7.1
To troubleshoot Anypoint Connector for Amazon S3 (Amazon S3 Connector), become familiar with the information about interpreting commonly thrown exception messages.
## Enable SSL Logging
Enable SSL logs to investigate an issue related to TLS communications.
Set your SSL log level depending on your required level of detail:
  1. Enable only SSL log details:
`javax.net.debug=ssl`
  2. Enable only handshaking details. (The handshake protocol is a series of messages exchanged over the record protocol.)
`javax.net.debug=ssl:handshake`
  3. Enable handshaking details and SSL details at the same time:
`javax.net.debug=ssl, handshake`
  4. Enable the dumping of all details and traffic data:
`javax.net.debug=all`
This option is very verbose and under normal circumstances is not necessary.   
---  


SSL logging results in a performance impact for HTTPS or other TLS connections. Enable SSL logging only to troubleshoot a specific issue and do not enable it for extended periods. SSL logging produces a significant amount of log messages and can inundate your log file if it is left enabled and unattended.   
---  
To enable SSL logs:
Set the debug parameter as an argument in the runtime configuration for the application.
  1. In Studio, right-click on the project and select **Run > Run Configurations**.
  2. Go to the **Arguments** tab and add `-M-Djavax.net.debug=ssl` in the **VM arguments** section.


## Enable Verbose Exception Logging
Enable verbose exception logs to show a complete stack trace of the error instead of the default truncated output:
  1. In Studio, right-click on the project and select **Run > Run Configurations**.
  2. Go to the **Arguments** tab and append the arguments in the **VM arguments** section to add the `mule.verbose.exceptions` property. For example:
`-XX:PermSize=128M -XX:MaxPermSize=256M -Dmule.verbose.exceptions=true`


## Enable Verbose Logging
To get a better understanding of why an application’s interaction with Amazon S3 Connector is failing, temporarily enable verbose logging for the connector.
Remember to always disable enhanced verbosity after troubleshooting, because it can affect your Mule application’s performance.
To enable verbose logging in the configuration file:
  1. Access Anypoint Studio and navigate to the **Package Explorer** view.
  2. Open your application’s project name.
  3. Open the `src/main/resources` folder.
  4. Open the `log4j2.xml` file inside the folder.
  5. Add an `<AsyncLogger>` tag inside the `<Loggers>` tag:
```
			<Loggers>
				...
				<AsyncLogger name="org.mule.extension.s3" level="DEBUG"/>
				...
			</Loggers>
```

  6. Save your application changes.
  7. Click the project name in **Package Explorer** and then click **Run** > **Run As** > **Mule Application**.
