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

[Mack Hendricks]

Hey All,



I get this message when trying to route request to a WebSocket client:

Here is what my location table looks like.  It should try to send the call to  sip:98.209.240.245:56291;transport=ws

The Websocket list looks like this:


Server01:~# kamcmd ws.dump
{
	connections: {
		8: wss:98.209.240.245:56291 -> wss:134.122.27.49:4443 (state: OPEN,  last used 47s ago, sub-protocol: sip)
	}
	info: {
		wscounter: 1
		truncated: no
	}
}


I’m not sure what I’m doing wrong.  Any ideas?


Thanks in advance
