Cannot connect to Xbox one live all of a sudden

Same thing is happening to me. All of the sudden I cannot connect to Xbox live. Nothing has changed on my end! What's up??

Hey iJuice!

Glad everything got worked out for you. Thanks for circling back and letting us know!

UPnP is over written by DMZ and dmz is over writen by portforwarding they dont interfere with each other if they all go to the same address (well other then port forwarding will do all the work other 2 just kinda sit there).

Remove port forwarding from your router. in fact restore it to factory defaults and do the same on your xbox (sys setings > network settings > your network > configure network > additional settings> restore)

Port forwarding is likely cause of your current internet issue on your pc. the router page should still load though.

i would re-download with out deleting and if it still gave me issues i would then delete and redownload. after that its time to delete and reinstall the updates (on storage select primary storage unit and pres rb lb x rb lb x ) after deleting the updates
run xbox live test and re-download them.

I tried clearing the system cache and it didn't work. I'm getting a "problem loading page" error upon trying to go to the sign in page on my PC, so I've been using my phone to access the forums because I can sign in that way. Should I still try to delete
and re-download my profile?

Yes, just one. Like I said, I didn't have all three active simultaneously and I just disabled UPnP and forwarded the ports again, still to no avail.
