When facing connectivity errors, what should you prioritize examining?

In troubleshooting connectivity errors, it is essential to prioritize examining source credentials and endpoint accessibility. This is because connectivity issues often arise from either authentication problems or the inability to reach the designated endpoint due to network issues or misconfigurations.

Source credentials are critical as they ensure the system can authenticate properly with the endpoint. If the credentials are incorrect or have changed, access will be denied, resulting in connectivity errors. Therefore, verifying that the correct and necessary credentials are being used comes first in the troubleshooting process.

Endpoint accessibility is equally important. If the endpoint is unreachable due to network issues, firewalls, or incorrect configurations, the system will not be able to establish a connection, which creates a barrier in the integration or functionality. Ensuring that the endpoint is up and running, as well as checking for network connectivity, will help in diagnosing where the issue lies.

In contrast, focusing exclusively on the configuration of the database may not yield results if the underlying problem pertains to authentication or network connectivity. Issuing an HTTP request to the endpoint could be a valid step in the process after ensuring credentials and accessibility, but it is not the first priority since the request will fail if the other issues are not resolved. Similarly, end-user notification settings are generally not related to backend
