Detached mode didn't work

[vadi2]

I tried out the new detached mode, but it didn't seem to work. Here is my run: https://github.com/Mudlet/Mudlet/actions/runs/9233166348/job/25405273411?pr=7244

I tried connecting to the machine right after SSH was setup, but all I got was this:

(base) vadi@barbar:~$ ssh 87fhjEtqqmk99yu4Z4YPLFWT6@nyc1.tmate.io
The session host disconnected 1 minute ago.
Hopefully it will reconnect soon. You may try again later.
Connection to nyc1.tmate.io closed.

This is while the workflow was running and I should have been able to connect to it.
