Launcher keeps disconnecting the internet

Hello,

when i log into my Epic Games Launcher i got long waiting times with errors at the end. I googled alot and tried stuff but nothing helped.
I run as administrator, i opened TCP and UDP ports 80,443 and 5222. I added the " -http=wininet" to the shortcut path.
I also tried the 32 bit and 64 bit version of the launcher.
What i noticed is if i try to login i get disconnected from other programms i.e. steam.
I reinstalled the Epic Games Launcher (clean reinstallation) and also noticed if i just wait some time it starts patching the launcher but it goes like: 19kb/sec for 2 seconds then 20 seconds of 0kb/sec (disconnect/no connection). Also gives me the red triangle saying the connection is lost, restart the application.
here is my dxdiag and my debuglogging:
I hope some1 can help me
