X2Go client worked fine for me under Mac OS X for a while and suddenly it stopped working giving me the "Can't connect to X-Server. Please check your settings" error. I followed the steps outlined above and was still receiving the error. I resolved it by quitting X11.app and deleting my X11 preferences file located in /Users/Username/Library/Preferences/org.x.X11.plist . Once deleted, I started X11.app again, configured it to "Allow connections from network clients" and X2Go client worked again. I am currently running Mac OS X 10.6.3 although I am unsure which version I was running when I installed X2Go client and had it working initially. I hope this helps someone.
