There are many reasons why the sharing link failed: 1, and the sharer canceled the sharing himself; 2. The sharing content is illegal, and the illegal sharing is cancelled after being reviewed by the official background; 3. The shared files will be antivirus in the background. If a virus is detected, the sharing will be cancelled.

Your share can always be accessed as long as it is not canceled. I don't know much about your problem, because I don't really love you. I'm 10 years old!
