Hello, the poster

It may be that the plug-in was deleted by mistake, or the Internet speed may not be smooth. Or it is stuck, try refreshing it (it may also be because the other party has heavy traffic, try it later)

Detailed analysis

1. Firewall (or browser security level) The setting is too high

2. There may be a problem with your flash player. It is recommended to update or re-download the latest version.

3. Internet speed problem. You can try refreshing it

4. Browser problem. It is recommended to clear the cache or reinstall (it may be incompatible, change another one)

Or the browser crashes, you can use Tencent Computer Manager - Computer Clinic - Internet abnormality, IE repair. If IE is poisoned, you still need to try antivirus.
