[X2Go-User] socket bind error with Windows client

[Hanno Foest]

Hello,

randomly (about one in three attempts) when I try to connect to one of
my x2go sessions, it doesn't work and I'm getting the error

Can't create SSH tunnel for the start of the X2GO Session (NX):
socket bind error localhost:57030

(translated from German, hope it's correct).

netstat doesn't seem to list the port as being in use. So far I didn't
find any other way to recover the situation other than rebooting, which
is a bit of a hassle sometimes.

Client is "X2GoClient V. 4.1.2.2 (Qt - 4.8.6)"

Curiously, the second x2go session I use to seems to connect without
issues all the time.

In case it matters: The machine is connected using OpnnVPN. Turning off
antivirus didn't make a difference.

Any ideas?
