i found this post, but i dont know how to turn off LTE...: Have solved the problem. I have both the DSL and LTE connection active on my Telekom router, the Speedport-Pro. I have now switched off the LTE and it works. Hope I could help someone. To all others, thank you for your help.

Soo... i installed VPN and its worked, also i could login to faf without VPN next time,hope i will never need VPN again.
