How to fix error code 300202 in Diablo 4

Error code 300202, the hardest boss in Diablo 4

Diablo 4 boasts a robust, online shared world. However, when you’re out adventuring by yourself, it can easily feel like a fully single player game. It’s times like these that connection issues can feel incredibly jarring, which is the case with error code 300202.

In short, error code 300202 indicates that Blizzard’s servers just can’t connect with you in Diablo 4. This may, potentially, happen due to some connection issues on your end. However, if you’ve otherwise had a good time playing the game, the problem most likely lies with Blizzard. We’ve seen quite a few connection issues crop up since Diablo 4 launched, including invisible walls that lock players out of areas.

If you happen to play the game during times of congestion (which is common during any launch window), you’ll probably encounter an issue like this sooner than later. In other words, you may just have to wait until the servers cool down.

If you see error code 300202 pop up, check if Blizzard is conducting maintenance on the game. Diablo 4 won’t necessarily tell you this beforehand, so you may need to check for yourself online. Blizzard’s customer support Twitter account may offer some answers, and Blizzard’s official support portal could also provide some insight. Otherwise, if your internet connection works on your end, there’s isn’t a whole lot you can do.

It’s a bummer to get locked out of a game you enjoy, but hopefully the experience will feel smoother when you try to play later.
