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

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

So was the problem was domain name resolution rather than the port?<br>

If the problem was domain name resolution instead of being related to<br>
the port then when DNS returned the correct address then of course the<br>
TCP connection on that port would work okay.<br>
<br>
Since Connexion does not force rotation of IP addresses it means they<br>
do not change very often, if at all. Mine has not changed since<br>
installation. I suggest noting down the IP address of your home<br>
system and taking it with you when you travel on your mobile machine.<br>
Then if for whatever reason your dynamic IP address resolution fails<br>
you can fall back to using the saved off IP address.<br>
