troubleshooting connection refused error on linux

[kadirayk]

I have successfuly built source code on ubuntu (32 bit). I am trying to run neverball with ga-server-event-driven, game starts fine but client is not able to connect to the server. The behavior is the same when I use the pre-compiled binaries for Linux. Is there a way to troubleshoot this problem to see the error in more detail?

here is my server's output:

Hi @kadirayk I am facing the same issue with Assaultcube. Were you able to connect the server and client successfully? Please share what you did to resolve this connection issue.
