I'm seeing the following errors trying to connect to a new machine running server version 3.0.99 using the browser client:

The client reports: Resuming Aborting Error message appears:

The remote proxy closed the connection while negotiating
the session. This may be due to the wrong authentication
credentials passed to the server.

Finished

I ran a check for sessions and there is only one existing session.

I've triple-checked the credentials and logged in on command line using them.

Here's what we have for x2go processes:

ubuntu 3219 1 0 Feb02 ? 00:00:50 /usr/lib/x2go/x2goagent -dpi 96 -D -auth /home/ubuntu/.Xauthority -geometry 1005x552+113+232 -name X2GO-ubuntu-51-1296672519_stDGNOME_dp24 :51 ubuntu 3690 1 0 Feb02 ? 00:00:00 /bin/bash /usr/bin/x2goruncommand 51 3219 ubuntu-51-1296672519_stDGNOME_dp24 30008 gnome-session nosnd D root 15119 1 0 Feb02 ? 00:00:04 /usr/bin/perl /usr/sbin/x2gocleansessions

So there is an existing session. I got detached from it when the browser crashed.

It seems as though the client should either automatically attach to the session or present the user with the list of sessions to take some action.
