This has been happening to me for about 4 years now in Black Ops 3 and 4; I always get the same error. I contacted Activision support and did everything they told me to do: connect via Ethernet, open my NAT, uninstall and reinstall both games, clear the cache for both, and talk to my internet service provider to see if there was any kind of problem, but there isn't. I’ve tried using a different account in both games to see if the issue would just go away, but it’s the same situation. Interestingly, when I play Zombies in Advanced Warfare, Infinite Warfare, and WW2, this doesn’t happen—I can play those games as much as I want without getting kicked out of the match. I don’t know what to do anymore. Does this happen to anyone else? And if so, how do I fix it? (If I can even fix it.) I want to keep enjoying Zombies in Black Ops 3 and 4 :c
