Hi.

When I try to reconnect to a X2Go session it sometimes fails, if I use
x2goclient-cli I can see this error message on the client side:

channel 1: open failed: connect failed: Connection refused

I've have experienced this problem for a long time (years), but haven't
reported it because I haven't found a way to reliably reproduce it.

I did some troubleshooting yesterday and may have found a clue, this was
logged in the X2Go debug log (server side) at the same time that the
reconnection failed:

It looks to me like it could be a conflict between x2goresume-session and
x2gocleansessions? While the session is being resumed, it gets cleaned up
and suspended?

Cheers,
Daniel

What X2Go Server version are you using? This is a know issue in X2Go Server <= 4.0.1.15.

I am about to release 4.0.1.16 which should solve the issue.
