Xbox one NAT type unavailable

Thanks everyone. Good to see this post Meckonomen. Tinkerbeard what is TS? Transport system?. Meckonomen I'm reading the post. Listen, as you Swedes out there what should I demand or ask when I call ISP. I don't want to call and ask to speak to the manager. I just don't get how when I call they just act like i never heard of Teredo. I think we are all great full for the posts. Keep up the good work. And even you all with different internet providers, let us know what they said . Because it might be time for a change.

Wouldn't everyone have this problem if it was on MS end?

I have no issue with or without ipv6 enabled in my router. I have Telia and use a Asus AC86U router.

Good question. I suppose it's possible that it only affects some ISPs, due to how they route their traffic. But I'm out of my depths here. Like I said earlier, I've never come across Teredo up until now.

Well, I have even tried to turn on VPN with public ip and open ports with no difference just to try if the data is taking another way.

Hi everybody! Just wanted to share some hopefully good news. If you have not already seen. Last night Xbox Supported tweeted out:
” If you're in Sweden and are seeing connection issues or a Teredo error when testing your console NAT, we are investigating this now! We will post updates here and at xbox.com/status”.
