What is the problem that the Golden Boy Rubik's Cube can't land? Error displaying user name or password?

I have been using the Golden Boy Rubik's Cube recently, and I have encountered this problem. The customer service staff gave me a comprehensive reply, hoping to help you.

(1) Check whether the computer display time is consistent with the local time of the current month;

(2) The input method is wrong, please use half-angle input;

(3) clear the browsing cache;

(4) If the user name or password is wrong, you can use the "Forgot Password" function in the registration interface to retrieve the password.
