That's the problem!  It's Montanna!  No, wait...  :-)

It's always disconcerting when things fix themselves.  I am much more
comforted when there is a definite change which fixes a definite
problem than when things spontaneously repair.

So was the problem was domain name resolution rather than the port?

If the problem was domain name resolution instead of being related to
the port then when DNS returned the correct address then of course the
TCP connection on that port would work okay.

Since Connexion does not force rotation of IP addresses it means they
do not change very often, if at all.  Mine has not changed since
installation.  I suggest noting down the IP address of your home
system and taking it with you when you travel on your mobile machine.
Then if for whatever reason your dynamic IP address resolution fails
you can fall back to using the saved off IP address.
