I got now for some days the problem that i can connect to the KW online servers but didnt get any ping to players.
I allready tryed to set on my router an optional port on 16000 which was written on the help section and set 16000 ingame as well. Didnt work.
The game works only without problems with "Windscribe" the VPN programm but its not a totaly conclusion for me cause its beside the free GB costing.
Was asking on Discord but dont find any solution anyway.
