80504: An internal server error has occurred.

This error means Proxy could not complete the request because it encountered an internal server error while processing it. In Twilio API responses, a 500 status indicates an internal Twilio error.

• Proxy encountered an unexpected internal failure while handling a Proxy REST API request.
• A storage or downstream Twilio component used by Proxy failed during request processing.
• A current Twilio incident or degraded service is affecting Proxy or the wider Twilio platform. (help.twilio.com)

• Retry the request after a short delay. If you retry automatically, use exponential backoff.
• Review the Twilio Debugger to inspect the error event and confirm which request failed.
• Capture the Twilio-Request-Id response header from the failed request. Include it in your investigation or support case.
• Review the Twilio status page to see whether an active incident is affecting Proxy or related platform services. (help.twilio.com)
• If the error continues, test the same request with curl and contact support with the request details and request ID.
