Hi. I play Forza Horizon 3 on PC and when I try to join online content I receive "UNABLE TO JOIN SESSION. FAILED TO RESOLVE SERVER ADDRESS. CHECK YOUR DNS SETTINGS".

So in the Xbox app I go to "Settings - Network" and NAT-type is set to Open but Serverconnection is set to Blocked.
I have tried all the MS suggested solutions and none of it worked. Win 10 Xbox games online are using the hidden network adapter called "Teredo Tunneling Psuedo-Interface" and you can check the status of this adapter using the following command in CMD: "netsh interface Teredo show state".

So when I connect the PC directly to the network wall socket playing online works fine and I get the folloing Teredo status:

Teredo Parameters Connected directly to the wall socket

Server Name : win1710.ipv6.microsoft.com.

But when I am connected to Deco M5 using Wifi or Wired I get the folloing Teredo status and then it doesn't work to play online:

Any suggestions on how to solve this?
