[SR-Users] TCP/TLS connection (id: 0) for WebSocket could not be found

[Mack Hendricks]

Hello,

I’m running kamailio 5.1.10 (x86_64/linux)

The connection_id in usrloc is -1 for some reason so the id doesn’t match for sure.  But, I thought that it would match on the received address of the WS client because the output from ws.dump shows that the connection address and port matches the received address and port in usrloc.

Any suggestions?
