it doesn't seem like anything I've run into before.  Any ideas?

The tshark output isn't verbose enough to tell for sure whether this is
the cause, but krb5 in Fedora 30 no longer supports various weak
encryption types. I'd recommend to double check the available enctypes
for your server's nfs principal. More details at:

Kind regards,

Thanks for the response.  Turns out to have be an incorrect FQDN in use on one
machine - the OS difference was a coincidence.
