What is the reason why the free online course of the smart education platform in primary and secondary schools is not stuck?

There are several login methods for smart primary and secondary schools, one is account password login, the other is SMS verification code login, and the third is WeChat or QQ scan code login. No matter which login method, we must ensure the smooth flow of the network. If there is nothing wrong with the network, it may be that the computer or mobile phone is too stuck.
