Youku's password and account are correct, but you can't log in.

This problem is solved as follows: 1. Open (taking 360-speed browser as an example) → Customize and control 360-speed browser → Options → Advanced options → Privacy settings → Clear browsing data →

Special instructions (check all as far as possible) → Clear browsing data;

? Switch the browser to compatibility mode → Log in to Youku again → Wait a moment (there is no other operation here) → The following screen appears.

→ View the certificate → Install the certificate (after completion); Return to this screen and select Yes. Then log in to Youku again and select Remember Password. At this point, the login problem of Youku can be solved. (For other browsers, please refer to "Clearing Browser Data". )

? The main idea is to clear the old data and get the information exchange security certificate with this website again.
