Server connection blocked - Forza DNS Issue

Hey guys,

I´ve a problem with my xbox app for Windows.

I´d like to play Forza 3 online on my PC but i can´t because the server connection is blocked. I opened the ports on my speedport router and firewall and tested everything. Other PC´s in our network didn´t get the issue in the xbox app, only my PC.

I test it in a friends network (his Pc work ) but my pc didn´t ...--> server connection is blocked.

I don´t know what it should be...

After reseting the router i can play forza 3 online for only 10 hours or something like that, and at the next day--> same **** again

I hooope so much somebody can help me! It would be sooooo awesome!

Thank you!

Greetings from Germany!

Your DNS server can't resolve Xbox live server names.

I figured it out....apparently someone had blocked my xbox from connecting through the gateway.....therefore giving me the DNS server issue. Once i unblocked it it connects just fine now

 

Server connectivity blocked after re-installing teredo

i have just downloaded Forza Horizon 3 and unlocked the online mode but every time i try to join a open lobby a DNS error comes up. i have checked the XBOX app's network settings and my NAT type is working fine but the server connectivity is blocked.

 

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.

 

Hey,

The firewall is enable and i only have the Windows Defender on my PC, and i think it doesn´t bloked it.

My Nat-Type is open in the xbox app, and the Ports are open, any other ideas ?

Thank you so much!
