If the theoretical training can't log in, it must be being maintained or updated in the background of the system. You can log out and log in again.

If you already have the account number and password of the education and training platform, and the account number is still valid, if you can't open it, it may be that the relevant course content has not been opened on the platform, but generally these will be prompted.

For example, the course has not started yet or you don't have permission.
