--- Comment #2 from wolfgang.liessmann@web.de ---
There is no option '-d', see output below.
Do you mean '-vvv' for increasing the verbosity level?

SSH log (master and client)

> debug1: forking to background

unfortunately logs from the mux master process are lost after this
point. Can you reproduce the problem without -f on its commandline? If
so, please try to catch debug logs from it in that state.

I assume both commands are being run in the same directory? Does "ls -l
socket.tmp" show a socket on the filesystem when you run the client?

--- Comment #9 from wolfgang.liessmann@web.de ---
Running the master process in the foreground with only 'ssh -vvv -MN -S
socket.tmp host1' (and then the client process in a different terminal)
works well.

But any background execution of the master process (with '-f' and
either '-o ControlPersist=20' or 'ControlPersist=yes') seems to fail
and the process disappears.
There is no ssh process shown in the output of 'ps -ax' (Mac), and
trying to bring it into the foreground with 'fg' fails ('fg: no current
job').

I don't know the previous openssh version. But on the server side it
still says 'OpenSSH_9.2p1, OpenSSL 1.1.1s 1 Nov 2022', maybe this one
worked.
