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

Hello,

when id is 0, then the search of the connection is done by target
address. For some reason, the destination is not matching the
connection. Try to print $nh(u) before relaying to see where it is
supposed to be sent.

Cheers,
Daniel
