I had changed the ssh port thru /etc/systemd/system/ssh.socket.d/override.conf:

[Socket]
ListenStream =
ListenStream = 24427

The team requested to have that returned to the default port 22. So I
changed the file to

[Socket]
ListenStream =
ListenStream = 22

With a recent update I could no longer ssh into the machine. Two solutions:
1. Use sshd instead of ssh.socket
2. Remove or rename the above control file so that it is not read.

I.e. having port 22 defined in the controlfile breaks access. Annoying.
A fix will be highly appreciated.

Others ran into the same issue:
