# Troubleshooting

* Check if the TPA endpoint is properly configured and is open to external traffic
* Check if the config.yaml file in the tpa has correct values
* After making changes to the proxy, make sure to save and deploy the latest revision of the proxy
* If TLS handshake fails, the following config for ssl, can be used to identify, if this indeed was the issue :

  ```
  <HTTPTargetConnection>
    <SSLInfo>
    <IgnoreValidationErrors>true</IgnoreValidationErrors>
    </SSLInfo>
  </HTTPTargetConnection>
  ```
* Observe that the `IgnoreValidationErrors` has been set to true
* A debug session can also be started for a proxy, which is not exhibiting the expected behaviour, by navigating to the proxy, clicking on Debug in the upper left corner, and then starting a debug session, this will capture the entire flow of the proxy, when a request is made
