StarCraft II: Why is the international service account invalid?

First of all, StarCraft II is an online game, which requires players to have a valid account to log in. The international service account number may be invalid for the following reasons:

1. The account and password entered by the player are incorrect. You can try to re-enter or retrieve/reset the account password.

2. Players are banned, probably because they violated the rules of the game or used illegal plug-ins. At this time, you need to contact the game customer service for consultation.

3. The player's area can't log in to the international service, which may be caused by the game policy or regional restrictions. At this point, you can try to change the region or sign in with another account.

In short, if the international service account is invalid, players need to carefully check their account information and game rules, or contact the game customer service to get a specific solution.
