(The subsequent IPv6 stuff is just collateral damage.)

"Connection refused" sounds like the server process simply isn't
listening on that port. Client logs aren't going to tell us much here.
Is there anything useful in the server log? Would it be possible to stop
the server and bring it up in debugging mode (with -ddd) and see what it
says then?

Thanks,
