What the message tells you
“Sorry we have trouble while authorizing this application” means an application could not complete an authorization step it expected. It does not identify the cause by itself. The service it contacts may be unavailable, its request may be rejected or the installed version may no longer be supported.
What it does not prove
The message is not proof that your movie was removed, that your device needs another player or that a new package will work. An installer can open successfully while the remote service behind it no longer responds as expected.
Check the failing stage
- Note the app name, version, device and complete error.
- Check whether ordinary web access works on the device.
- Distinguish an app startup error from a failure after choosing a particular episode.
- Use support information that applies to that actual application and version.
Repeated installations cannot restore a retired service. Cinehub's browser catalogue is a separate way to search and save titles here; it is not a repair utility for historical APKs.
If your problem is instead “episode not available right now,” open episode help. If the website itself will not load, start with page and connection checks.
