Results of some further testing:

* The problem seems to happen only when connecting to the server running 
on openSUSE Tumbleweed.  Connecting to a server running on another 
machine (running openSUSE Leap 15.3) still works.

* The problem doesn't seem to have anything to do with the particular 
account I'm connecting to.  I still get the automatic disconnect when 
logging in as a different user.

* Here are the server logs with logging level set to "info":

I still don't see any obvious culprits but would welcome any pointers...
