Microsoft Teredo Unable to Qualify

I've been having this issue forever, games like Ark Survival Evolved and Astroneer my friends cannot join my invites on Ark but joining from my profile works, games like Astroneer if I try to join somebody else it doesn't work but if they try to join me it works, now I've tried just about everything from powershell and command prompt but it doesn't work, i've also tried opening registry editer and setting the value to 0 and it still doesn't work. I don't know how to fix it because I have tried fixing it before and then when it works it doesn't work when I restart my pc again.
