Hello,
did you print the log message just before t_relay()?
Can you also print the tcp and tls connections via rpc? I am not sure if
the websocket keeps a separate list of connections, but tcp/tls should
have the lists used for routing.
It would be better to upgrade to 5.3, because 5.1 is out of maintenance
and if there is still an issue, it is easier to troubleshoot and fix.
Then you can backport locally to 5.1, if you have to run that version on
specific systems.
Cheers,
Daniel
