Hi,
both x2goclient for windows 4.1.2.2-20200213 and https://code.x2go.org/releases/binary-win32/x2goclient/heuler/mingw32-4.8/qt... are crashing during connection establishment when using a proxy (output from the debug build):

and then x2go completely vanishes.
Any ideas how to debug this further?
