The call.in-progress.error-vapifault-worker-diedcall.in-progress.error-vapifault-worker-died error indicates a failure in the Vapi processing pipeline, often due to configuration issues or unexpected inputs. As a first step, review your assistant and workflow settings in the Vapi dashboard to ensure all required fields are correctly filled and no misconfigurations exist.

"Could you please run these two telnet tests from your side and let me know the results? I'm getting the exact same behavior."

telnet 44.238.177.138 5060 (Should CONNECT

)

telnet 44.229.228.186 5060 (Should FAIL or TIMEOUT

)

"I need to confirm if the second IP is unreachable for you too, which would indicate a routing issue outside of my local network."

Both the ip address are correct but you will usually get a request from the first IP.
