Tried that. No joy.

Note that I get logged in just fine. I can run commands just fine
and everything works - for 55 seconds or so.

Further testing: It looks like the problem is from the client to the 
server because I can do 
   % date ; sleep 60; date
   Thu May 28 15:44:54 EDT 2020
   Thu May 28 15:45:54 EDT 2020
   %

Then, at this point, I can not send anything to the server - no
response of ANY kind. But I can open a new ssh session and it works.

I can also log into the server and "write" at myself and see the 
message:
   %
   Message from wayne at server on pts/1 at 15:48 ...
   EOF

Eventually, ssh dies and prints:
   Fssh_packet_write_wait: Connection to 172.16.6.1 port 22: Broken pipe

So, something with OpenVPN is timing out such that I can not send
from the client, after about a minute.
