Call of Duty Network Error 4A28—Unable to Connect Since Yesterday

I’ve been unable to log into Call of Duty since yesterday due to a network error (4A28). Whether I use Wi-Fi or mobile data, I can't connect to the game at all. I’ve tried uninstalling and reinstalling the game, but the problem persists.

It seems like a widespread issue, as many others have reported the same problem in the Play Store reviews, saying they can’t access the game either.

Please investigate this general connectivity issue and provide a fix as soon as possible. It's frustrating not being able to play, and we need a solution quickly.
