Why is the verification code of the King's camp wrong?

This is usually caused by an error in the system.

Players are advised to click on the account switch first, and intentionally enter the wrong number. It will let the player enter the verification code. After entering, it will show that the account number or password is wrong, then re-enter the correct account number, and click Login, which is generally ok. Another possibility is that the player did enter the wrong verification code, so it is suggested that the player try to enter the verification code again.
