I am investigating

Ok I think the Problem is simple: I should rename the button, because its purpose is confusing. As well as gray it out when there are 0 servers configured. When I never add a server config and press new session, I get an exact copy of your error log.

You either need to use Direct Connect or click the Settings Icon Button in the Top Right Corner.

Then add a new configuration for your server:

Then at least fill out these three:

If that wasnt your problem feel free to report back.

I created #176 To address this confusing part, that I was blind to as the creator.
Thank you for giving the program a shot and especially reporting your problems, so I can improve it <3.

PR #178 will resolve/close this issue, if this does not fix it for you, then please reopen.
After merge, a new release can be expected within ~5 hours or so. The release cycle is very long because of many checks running.

EDIT: 1.3.0 released with better user experience.

1.3.0 Release stalls for flatpak unfortunately, I have to wait for flatpak admin input.
The flatpak also is available as an artifact attached to the releases page in github. But also your problem can be solved by adding a server in the settings.
