Hi, I might add that it’s worth checking TCP keep alive from both client and server.

There are many different reasons for this error. With just this one line description and no more context it isn’t possible to say why it is occurring.



The most common cause of 477 errors is issues with the TCP/TLS connection to the far end. Have you tried capturing a trace of the call attempt? Have you verified your TCP/TLS settings are correct and are aligned with what the far end expects? Have you verified the message is being sent to the correct remote target to begin with?
