Why can't I connect to any game servers?

Hi Uriah!

What exactly is your Xbox console model/generation?
May I know the exact error message you're getting there?

Please try to power cycle your router/modem as well. Unplug it from the power source and wait at least 5 minutes before turning it back on.

Open NAT type is always going to give you best connection to servers/games.

The number of people using the router can also affect it as the router could possibly be getting overloaded.

And the firewalls in place could also be stopping you. you will need access to the router to check firewall settings.

some games require certain ports to be open so checking with the game website could help you get some more information.

maybe speaking with I.T/TECH department at your uni/college might help as they will know more on the setups they have in place.

if you have moved from one i.p to another clearing your alternate mac address could help you significantly, go to settings-network settings-advanced-alternate mac-clear (your xbox will restart)

Too bad to hear this friend, see if this link helps you, the ideal to play smoothly is open NAT. Good osrte, I hope for sure !!

Hi SYN DemonWolf,

Thanks for reaching out to us in the forums for this issue. As you've indicated that you're in a dorm, you'll need to get in touch with your person in charge of the network hardware to get yourself set up in a situation in order to have the server
connectivity dedicated. As there are likely others trying to get squared away with getting multiplayer connection for their consoles, you may also need to set up a static IP and port forward to accomplish this. Regarding the UPnP issue, that is part of the
router settings for your internet source.

Here are a couple of handy support articles that can help you with asking for assistance from your RA or IT advocate:

UPnP not successful in your network settings

Network ports used by Xbox Live on Xbox One

Xbox One Multiplayer Game Solution

I hope that this helps out!

Let us know if you have any further questions.

If the previous suggestions are not working, you can try to have Instant On turned off and Power Saving turned on. This makes your console take longer to start when you want to play it but refreshes the UPnP when it is starting up to help certain routers
setup your NAT. I know it is not ideal but I have seen people use it as a work around for routers that may be hosting multiple Xbox systems and may not have the latest UPnP technology.
