I use Ubuntu on my servers and have never had a systemd / ssh issue.
Getting Tomcat to work with systemd can be tricky especially if your
startup sh script gets complex. I’m going to guess you probably have a
permissions issue. If you verified the config I go back and look at
permissions. I
Try changing the port, usually I run mine on 5150 or 2112. Some times like
one dude said earlier. Reinstall distro and start over. :(

If I just ran the ssh port forward in the background, I could get the
famouns "pipe broken" error. I was hoping systemd would restart if this
happened. I don't think it will, but I'll have to wait and see.
I have the Restart=on-failure. With Restart=always, it wouldn't run and
seemed to be restarting a lot. But, I didn't see any restart limit errors
in the logs, so I'm not exactly sure what was up.
Perhaps I'll look into the watchdog feature. I don't think this will get
me anything though, since systemctl status thinks everything is fine and I
have no reason to believe it wouldn't keep sending the necessary signal.
I'm thinking I'll have to implement my own watchdog feature, which is what
I was hoping to avoid.
I had a lot of issues. I attributed these to systemd. Really, I think it
was ssh. But it does seem that systemd is complex and might be a bit
fragile. Lots of logging was generated but not visible. Gemini/Google
suggest that these kind of "terminal configuration" issues can cause that
problem. When things get fixed, the log entries are there, but it's not
optimal.

It is a simple thing to make things complex,

Perhaps, but it seems to work intermittently and
unpredictably. I
looked for contention on the port, but couldn't find any.
....So, I rebooted the client and restarted the systemd unit/service on
the server
and everything works. Interestingly systemctl status for the
unit showed that everything was OK before the restart, but nothing worked.
During the course of all this I learned, what is perhaps obvious, that
SSH does a
lot of things at the terminal config level. If something in SSH
terminates at an unexpected point, things can be messed up. Reset should
fix this, but apparently not.
That's my story and I'm sticking to it LOL.
