Knowing the standard response is to say upgade to the latest,
I don't understand why existing installations are failing, with no change on either side of version.
That's why I call out some disconnect with the server information, unless the server information
changes with versions, making old versions not able to interact with the server data.
But I did upgrade already this host and client pair, grudgingly, because of the ripple effect across all the machine
installations. But the result is the same. I cannot connect.
