Warzone connecting to online services?

Have had a new computer since yesterday. I switched from PS4 to PC, only when I start the game does it get stuck on "Connect to online services".

I googled and found out that it could be due to the ports, ok. So logged into our router (Telekom Speedport) the ports are taken over from the COD side only it says it is not valid the port number what am I doing wrong?

In advance i have no idea but i would contact your internet provider and then ask activision or whoever is responsible for that and they may be able to tell you more. Ps sorry that I couldn't help

Hi, I would have hoped that someone might know their way around, but if there's nothing left I have to take the path.
