I would expect ssh to acquire a ticket for the remote host
service.  You can see your tickets with "klist", so that will
give you one side of the story.

Speaking of /etc/hosts, the host's own name as it comes out of
its own /etc/hosts has to match the hosts name as it comes out
of DNS.  So the fully qualified name must be listed first, not
second after the short name.
