How to fix this?

Here are eight fixes you can try out.

Restart

At times, a simple restart is all it takes to solve seemingly random issues. If you’re having problems with Blizzard, try restarting your game, PC, and router to rule out any possible connectivity issues.

Run the game as an administrator

Another thing you can try is to run the game with administrator privileges to see if that fixes the problem. Errors like these can often arise because of improper access to system resources or files that the game needs to run properly.
