Thanks for that. Can you run this on an affected server, after making some connection attempts:
$ journalctl -u ssh.socket -u ssh.service -b > ssh.log and share ssh.log? ** Changed in: openssh (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/2112611 Title: ssh -X and ssh -Y does not work to non-ESM enabled servers iin 22.04 Status in openssh package in Ubuntu: Incomplete Bug description: Until recently I have been able to ssh -X to my machines and run X applications such as synaptic remotely. Within the last two days this broke and I am not 100% sure if it is an issue with xauth or ssh but it will not start X forwarding, debugging just says it fails without much info. However, it works on all ESM enabled machines. These are all Ubuntu 24.04. The only difference I can see is some of the libs that xauth uses appear to be different. But I don't know the root cause, I just know it was working until recently and now it doesn't.
