When watching, the number of people who can browse online at the same time is limited. If the number of people exceeds the capacity of the platform, the platform will collapse. You just need to wait for a while, and then log in again. Another reason is that there are problems with the computer, such as the loss of key files, the deletion of plug-ins, or problems caused by water flooding in the computer. I suggest you go to the computer repair shop to have a check.

In addition, network reasons may also lead to things happening, but the current network is basically stable and can be basically ruled out.
