Ok i finally got it to work. Might be expensive, if you want to try the same method i used, thoug.
First i had to set up Tethering on my Phone.
Then i had to Activate a VPN Service on your Phone
after that i had to Connect my Quest through the Phones Tethering to the Internet
and finally i was able to connect to the servers. sometimes i get a higher ping then usual but im fine with that after going through Hell…
again thanks to everyone who tried to help me and thank you to the Support/Dev Team for answering me. I hope you all have a great life and that i will never have to bother you again
