trouble maintaining an open ssh connection past 20 minutes

[Frances B. Webb]

This is a problem that I noticed last summer when I updated to openssh 8.0 in the Cygwin package installer. At the time, I was able to resolve the issue temporarily by reverting to version 7.9. I applied updates this morning, and openssh 8.3 was installed, and the problem is back. It consistently loses connection to remote servers I've ssh'd to after 20 minutes, regardless of session activity.

I'm not sure what I may be doing differently that is triggering this issue. When I was struggling with the problem last summer I was connecting to a variety of machines both with and without VPN, and had the problem regardless. This year, I'm working from home and can't connect to any of the servers I work with except with VPN.

Please let me know if there's any other information I can provide that might help. I'd also like to know if it's still possible to revert to version 7.9 of openssh at this point.
