I connected the api key to my app but the movies are not displayed anymore?

Take a Test
Using a computer, desktop or notebook.
On some mobile devices this test may not work correctly.
In the URL below, change THE_KEY to your API Key.
https://api.themoviedb.org/3/movie/550?api_key=THE_KEY
Use this example to do a search using a new tab or window in your browser.
You will receive the basic data of the Movie Fight Club (1999)
https://www.themoviedb.org/movie/550-fight-club
If it works, your Key is OK.

When there is a problem, the TMDb Server sends a message.
Can you tell which message the server sent?
Here is a list of possible messages:

If it does not work, let us know right here.

Then your API Key is valid and working correctly.

TMDb does not have any APP.
This APP was developed by third parties.
Numerous APPs and Websites use TMDb data and images.
It is impossible to support third-party programs.
I suggest contacting the APP developers directly.
