Connection problems over lte / 4g o2 homespot

[Alma]

Hello,

does anyone have the same issues?
I have the 50 mb/s internet from o2 and cant get a stable connection in this game. It usually goes like this: I start the game, search for 3-5 stars connections and have to wait like 3-5 minutes for 1 player to join. after or even during the match it disconnects with differnent error codes: 10007 or 2100d for example, i got at least 5 different ones. and then i cant connect again. other times i cant even connect to the server. i opened the following ports and activated upnp like recomended. TCP ports: 80, 443, 20002, 30840, 30850, 30870
UDP ports: 30840-30859, 30870-30879
I also deactivated ipv6.
I can play halo mcc online without these problems. With DSL i didnt have these problems

the homespot router is connected to the pc over lan cable, not wireless

specs
