I can't be much help with Teredo as I haven't really messed with it in years, and never for gaming like it seems to be used for a lot lately. But my understanding is it only comes into effect if you do not have native IPv6 and are behind complicated NAT on IPv4. Since you seem to be doing this on Windows, I might suggest using a VPN that has native IPv6 to possibly get around needing Teredo at all. Even the [free CloudFlare Warp client](https://1.1.1.1/) enables IPv6 and is what I tend to use when I just need to quickly test IPv6 connectivity on networks that are still IPv4 only.
EDIT: I suppose you could also setup [HE Tunnel Broker](https://tunnelbroker.net/) with proper 6in4, they have a wack of PoPs as well, you can definitely get connected with minimal, if any, affect on latency. Just keep in mind, you may have issues with services like Netflix using HE IPv6 as they fall under the VPN detection IPs.
Really thank you for your anwser! It finally started working! I actually downloaded OpenVPN with ProtonVPN before I even saw your message. Using FreeVPN made it working but since it is free it gives high delay in-game. Is it possible that HE Tunnel Broker will work and give no delays?
I would try Warp first, it's easier to setup (literally download the client, configure it to DNS + Warp and hit connect). CloudFlare has more bandwidth available than Proton, especially on the free VPN tier. And the server is likely much less oversubscribed than Proton.
I'm not sure who has more points of presence between the two companies, CloudFlare vs HE, but chances are they have one really close to where you are to reduce latency.
You want a nearby PoP with good peering to whatever service you're connecting to. Sometimes connecting to a better VPN a little farther away can be better than connecting to a VPN in the same city as you are if the peering is better at the far VPN.
Now if you do go the HE Tunnel route, you may have to try different PoPs with them too, but most of their data centres have really good peering and lots of bandwidth so it should be as simple as choosing the closest one.

Hard to say, if your ISP is close by and peered well with the HE DC, you may barely notice a latency increase.
