Weird Teredo problem

blysten141 · Jun 9, 2020

After being fighting against the typical "Teredo can't Qualify" error, I found the way to fix it, or I thought so. As you can see in the picture below, the problem had to disappear, but when I join in the game (Forza Horizon 4) the online mode still not
working.

Its weird because in theory, the problem had to have been solved, but it isn't really when I join the game.

I already restarted the pc few times.

I will be very thankful if anyone can help me with this.

Hey blysten141,

So i see your NAT type is open and that your connected, the one issue that i am seeing is your latency 225ms is a bit hight (i have the same issue, i live in south africa), can i ask what your internet speeds are and when you play forza what region you are
trying to connect to (if you are trying to connect to a region that is far your latency is going to sky rocket and you wont be able to play).

My second question is are you playing over wifi or LAN cable, if its wifi that could be adding to your latency issue.

Do your friends also have the message in NAT type that teredo is unable to qualify and server connectivity is blocked ? Got the same issue here with my friend at least it they don't have this message on their xbox app it means the
problem doesn't come from the game rather weird w10 ms ****.

Well I gotta fix my problem. I just randomly read an old question by me and a user has proveded some common solution where you can find 'em already in the internet and he also has provided a very "uncommon" step!

I want to set the attention on some different where it's depending on your router model! Basically you should go into your routers UI and check somewhere under Internet -> Filter and lists (in my case its was and Fritz!Box 7530 AX) and there you gonna look for Teredo. If the box is checked, then you gonna uncheck it by removing the checkmark. Because if this is enabled, your router gonna block all teredo related connection due to you need that Teredo tunneling in Windows 10 beeing able to play crossplay and use the xbox partychat with xbox players. Basically you otherwise won't get through the teredo tunneling if this Teredo on your routers UI is checked! Make sure if you still have all those weird teredo issues, gonna give this a try and uncheck Teredo filter on your Routers UI!
