Any hints at all in the browser console? IS this normal hardware or a rpi?

What is your users default shell?

Commenting with the output of this would be useful

getent passwd server

[rwolf2467]

No, it's not a PI. It is a server hosted by the company Strato.

root@ubuntu:~# getent passwd server
server:x:1000:1000::/home/server:/bin/sh

"/bin/sh" as shell is certainly unusual (that's "bash", not "bash", and rather uncomfortable for a human). But I just booted a clean ubuntu 24.04 with cockpit 314, changed chsh admin to /bin/sh, and it still works.

Could you please try this:

• Log into cockpit, but not directly into the terminal page (i.e. URL should not end with /system/terminal)
• From the overview, open the JS console (Ctrl+Shift+K in Firefox), type window.debugging = 'all' and Enter
• Switch to the terminal page, wait until it says "not-found"
• Then go back to the JS console and type window.debugging = null to stop the flood (there's going to be a lot)
• Right-click into the JS console, "Save all messages to file", save it as console.txt or console.log and attach it here.

Thanks!

[rwolf2467]

Sure!
Here is the console log:

Ah, I think that may just mean that the /home/server directory doesn't exist? Perhaps you created the "server" user with useradd instead of Debian's adduser? The former doesn't create a home dir by default, and also has a very inconvenient shell (dash) instead of bash.
