COD: WarZone "Network connection failure"

Well, today I started playing such a game.
But when I lost a lot of matches, the screen began to hang and errors started to pop up.
After re-logging and turning the game on, my eyes showed the inscription “Cannot access the network service”.

What can I do in this case? Colleagues normally only play something like this to me.

Best regards KADUK
