Hello, apologies, I found the relevant Wiki page on how to collect detailed logging info. I've grabbed data from multiple sources on the client and server, but haven't been able to interpret the log outputs to understand what the problem is.
Apologies for the data dump, but here are the relevant logs. Again, I've tried to replace most identifying info with variable names.

We recently moved a server to a new network and x2go is not longer working. The x2go client crashes too quickly to view or copy the error messages that occur before it fails.
On the server side, I can see these messages in this in auth.log. I've replaced all possible identifying information (hopefully) with bash-style variable substituions (e.g. $USER). I apologize as this reduces clarity, but I don't want any identifiable details on record.

I'm not really familiar with things like this, but it looks like it is repeatedly creating new sessions, and then these sessions are closed (for some reason). I don't understand form these messages.
On the client side, this is as much of the log as I can get before the program crashes. I haven't been able to locate the x2go client logfiles .

Can anyone help me debug this? I need more detailed errors if I'm going to solve this on my own -- I can't really access all the error messages, nor interpret the errors available, at the moment.
Thanks in advance if you're able to help. Best, M. Rule.
