Xbox Networking, NAT Type Open, but Server connectivity Blocked

Born Potato · Dec 2, 2019

Hello, I will thank you now for your time this I believe is unsolvable, prove me wrong?

So, of course I have done a lot of troubleshooting already and this is what I have done:

I followed this:

https://support.xbox.com/en-US/xbox-on-windows/social/server-connectivity-xbox-app-displays-blocked

Which lead me to this after not being helpful:

https://support.xbox.com/en-US/xbox-on-windows/social/troubleshoot-party-chat

Which of course was also unhelpful so I followed some advice that it said it may be a update that I need so I tried updating and it failed like it had been for a while. Now that is not a problem completely clean installed windows and updated it and it did
not help.

Also few things that I think are notable:

*ATT internet w/ Arris BGW210-700 Gateway

*Have done both port forwarding and Dmz (of course not together and both work fine)

*I can play xbox games and even match make/talk in game, just cant accept invites and parties

*Have tried ethernet and wifi (idk why just thought maybe at this point)

*Last thing is I see party/game invites but when i click the check it opens xbox chat but not the party and when I click check on game invites it just does nothing. LFG works but without invites/parties it is worth less

I have an idea, can you connect your console wireless using your smartphone as a router via tethering? In this way you can try with a different/new connection, so if the problem persist, maybe is console related, if in this way all works fine, you know that
is a "your local network" problem and the console works.

Just to be sure in what direction you must move, ok?

I have the same issue. I tried everything on this site:

https://support.xbox.com/en-US/xbox-on-windows/social/server-connectivity-xbox-app-displays-blocked

My Xbox App Settings:

Internet: Connected

Live-Services: Running

Multiplayer:

NAT-Type: Open

Server connectivity: Blocked

Latency: 185ms

Paketloss: 1%

Any Ideas?

We are all experiencing this problems. Nothing from FAQ helps. Please see discussions thread also:

Hi,

We appreciate you for bringing this up. If the Xbox app server connectivity on Windows 10 is blocked, your computer was unable to establish a Teredo IPsec connection to the Quality of Service (QoS) server.

Failure to establish a Teredo IPsec connection to the QoS server can occur when the Windows Firewall is disabled, when security software has altered the Windows Firewall configuration, or when required Windows services have been disabled or stopped.

To properly isolate your concern, check the NAT type on the Xbox App.

1. Click the Start icon and open the Xbox app.

2. Select Settings > Network.

3. Under Network status, check the NAT type.

We're looking forward to your response.

it could also be a nat type issue run a network test on your xbox and see what nat type you have. you can also refer to this: nat type and
if you need to open ports because of a strict nat you can refer to this page for opening ports:

open ports
