For some reason I can't connect to my PG 10.6.1 Server (running on =
Ubuntu) from my Windows installation (run via Parallels on my Mac), no =
matter what app I use (tried psql, PGAdmin and my own app).

When trying to connect from PGAdmin 4 the server logs say:=20

("konnte Daten vom Client nicht empfangen" means "couldn't receive data =
from client")
PGAdmin says the usual " Unable to connect to server:..."
No issue connecting from the Mac.
I see in the logfile that other windows users did connect successfully =
from their windows boxes so I am ready to believe that maybe my =
Parallels somehow disconnects the connection quickly or something.
Another strange thing is that if I try to connect from my Xojo app =
(which uses libpq internally) it says:SSL error: unknown protocol. I had =
no issue connecting last week from that installation so I am at my wits =
end...
