It didn't take long for Blizzard to fix the server issues, and the company is already working on this problem, so players should keep checking back for updates on the issue.

Unfortunately, if neither of these fixes works, the only other way to use that character is to play offline until the issues are fixed. Players should quit the application and reload it, then select the character getting the error message and try to create a game. Diablo 2: Resurrected must be shut down completely for this method to work, so simply backing out won't be enough. Players who are still getting the error message after this step can completely close the application and try to reload it. After the new character is made, they can return to the character selection menu and choose the character that was getting an error message, then try to create a game.

Diablo 2 Resurrected has plenty of characters and classes to choose from, but players don't need to focus too much on their choice, as they won't necessarily be starting a game with this character. First, players should try to create a new character.
