Server problem: there may be a problem with the server of the original knight prequel international version, resulting in the menu not being authenticated normally. This is caused by server maintenance, failure or upgrade. You can wait for the maintenance of the server. If the server fails or is under maintenance, the official will generally inform the player in advance and give the maintenance time. Players can wait for the maintenance to be completed before trying to connect to the server.

Network problem: the player's network connection is unstable, so he can't connect to the game server normally. This will cause the menu to fail to be validated, or the validation process will be delayed or wrong. Check the network connection to confirm whether the player's network connection is stable. You can try to switch to other network connection methods, such as Wi-Fi or 4G/5G mobile data network, and see if the problem is solved.
