The error message is indicating that you are trying to connect with tls1 which is old and considered insecure. Can you increase the version of TLS running on your bitbucket installation? Its possible that other pods may be tolerating the older version of tls but something within the AWX pod is preventing it from being used.
We highly recommend not using an outdated version of TLS. It is theoretically possible but we don’t have the resources to research how at this moment. If you figure out a method, please respond to this thread to share how.
