[X2Go-Dev] Problem connecting

I've always had no problems connecting to x2go with only port 22 open on my router. Just recently I've been unable to connect. I turned on debugging and see my client connecting in the system logs: client X.X.X.X has successfully resumed session with ID paul-50-1511705558_stDXFCE_dp32

However, on the client I get an error that says "could not establish connection to remote proxy" I see this error repeating when I run the client with a --debug flag: 2go-DEBUG-../src/onmainwindow.cpp:10759> "Searching proxy window: X2GO-paul-50-1511705558_stDXFCE_dp32" x2go-DEBUG-../src/onmainwindow.cpp:12465> "Searching window with title: X2GO-paul-50-1511705558_stDXFCE_dp32"

I'm not using a proxy for the internet.
