I have been asked to describe the bug here:

I am using x2goclient: 4.1.2.2 on Mac ARM  installed via Homebrew, primarily to access an Ubuntu server via SSH. I have been doing this largely successfully for years. Last week I updated to MacOS Sequoia. When I go to connect to my server from the GUI 'New Session' I consistently get 'Failed to connect: No route to host'.

If instead of launching X2go in the normal mac way by clicking on the app icon, i do in terminal
/Applications/x2goclient.app/Contents/MacOS/x2goclient
The same operation for 'new session' is successful. I see this output in my shell:

x2go-INFO-1> "Starting X2Go Client 4.1.2.2..."

I recently had an issue with another app after updating to Sequoia with a workaround: https://github.com/zim-desktop-wiki/zim-desktop-wiki/issues/2665 I am wondering if the issue is cmoparable here - some sort of environment variable or locale being required but not otherwise being sourced correctly since Sequoia

I have found a bug and workaround in x2goclient on MacOS Sequoia. I am trying to raise report/this but where?

The official wiki advice suggests applying to join the GitLab org - I've applied but I have to wait for admin approval.

There's an IRC/Matrix channel where it was suggested I also join the mailing list. The bugs mailing list 
does not appear to have been active for a decade although I have subscribed. A kind soul on IRC suggested also joining this mailing list but I am not sure that this is the right place to raise a bug report.

Without meaning to be rude about a great software project, the situation does seem a bit ridiculous. I run my own (much, much smaller) open source project onGitHub and if people want to raise an issue then they can just do that, ditto me for many of the other open source software projects I use. It's unfortunate that there isn't a clear and straightforward way here. 

If anyone is able to comment on the correct route to raise an issue/bug then I should be grateful, thanks
