Xbox cannot connect to any private game with friends

Hello!

I'm a Independent Advisor. I will be glad to help you.

Contact your Internet service provider and ask them to open these ports

Port 88 (UDP)

Port 3074 (UDP and TCP)

Port 53 (UDP and TCP)

Port 80 (TCP)

Port 500 (UDP)

Port 3544 (UDP)

Port 4500 (UDP)

Also ask it to enable UPnP in case you have it disabled.

Best regards.

Hey Brett, thanks for the thorough first post. From reading your post, it sounds like you likely have an invisible NAT issue. I'm taking it you're on a different ISP than your friend, correct? Also, your issue does persist when wired directly to the modem,
yes? I'm afraid that if you are on an invisible NAT (which would lay with your ISP), your only option will be to connect through a different ISP.

Always happy to reply. Best of luck with the ISP--please do keep us posted. And of course, feel free to
rate your forums experience at any point.

Thanks for the reply Mister Fitzer!

Connecting to the modem directly doesnt fix it, and yeah my friend is on a different isp.

Looks like its the ISP. Any word on people successfuly getting this issue fixed at their isp?

I dont have much choice in my neighbourhood unfortunately.

Thanks again!
