XBOX ONE - UPnP not successful

XBOX ONE - UPnP not successful
Hi,

I have the original Xbox and I have had it for years now, since December of its first release. I just recently got the message of UPnP not successful on my Xbox. The weird thing is I have not switched networks besides traveling and when traveling I am in
the same places I had easily connected to before. UPnP forces a strict NAT type on me when I never had the issue before the recent update to XBOX. I never had these problems when connecting to these networks before, but now the message will not go away no
matter what troubleshooting I have tried. I even tried to soft reset my console while keeping my games and apps and this changed nothing. I am tired of having terrible internet because my console is now glitched or there is a problem that I did nothing to
receive. I would like help in this area, so please get back to me.

:)
