Thank you, but i fixed everything now, also by using the informations on the website, but still i dont know if i might be able to play iron banner or how long my restirction will be. Do you have an idea? Again: Thanks for the answer :D

If you cannot connect after your restriction which the first time (was) 30-60 minutes then you can assume your restriction is 2 weeks. Since you didn’t resolve the internet issue before like you said you just fixed then unfortunately this is on you since you didn’t resolve it in the first place.
