I'm playing on Xbox One and I have the problem that many online games do not work properly. The biggest problem here is Call of Duty Modern Warfare (2019). Since about 38h I can no longer log in. I get into the game briefly, can join a lobby, play for 20 seconds, and get kicked out. Local mode also does not work because the connection to the host fails. When I'm thrown out and in the game's startup screen, I usually get error 65538 and error 66626.
The strange thing is that I also have the same problem with black ops 4 and also have to endure bad connections in other games, and that from one day to the next (the unplayability is limited to the Call of Duty games).
I've already tried almost everything. My Fritzbox updated, restarted, open type checked (exposed host on), teredo filter switched off, prioritization set up, the console is always assigned the same ip address (also correct on the console).
On the Xbox I checked dns (cloudflare dns), renewed the mac address, checked for damaged game data, uninstalled and reinstalled the game, restarted the console, changed the country, etc.
XboxLife and Call of Duty Server are doing well for everyone else (xboxlife also for me). I seem to be the only one with this problem.
The last idea I have is that the corona virus plays a role here and my provider is causing problems. However, I'm slowly becoming desperate and don't know what to do.
There's now a solution.
You already have the error messages error 65538 and error 66626, so get in touch with Xbox very quickly and easily, the answers immediately, the best thing to do is call there's a number for support. Have the errors ready with your ingame name and they will definitely help you.
If you have a cable connection, there can be temporary impairments because everyone is crouching at home and the network is sometimes overloaded (or the cable distribution box).
