API Key Invalid
My API key was working until last month.
However, When I checked my API key this month, I got 401 error with this message
"Invalid API key: You must be granted a valid key".
Can you explain me why my API key Invalid?

Better make sure your API Key has been canceled.
And the safest way is to do the test below.

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.

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

I got this error message instead of basic data of the Movie Fight Club

Also, when I check my api authentication, Still I got this message. "status_message": "Invalid API key: You must be granted a valid key."

Sorry I do not understand.

You did the test I indicated above and

1. received the correct data in the response.
   
2. received the same error message that you reported at the beginning.
   

Choose one of the possibilities.

Sorry, Now I understand.

The answer is 1,

I received the correct Fight Club Movie's basic "data", instead of go to https://www.themoviedb.org/movie/550-fight-club this page.

With this test we know that your API Key is still valid.

How or where did you do this check?
It was using "Try it!" in the Documents?

The "Try it!" option in DOCs it only works with the "Access Token Auth" option.
It doesn't work if you select the "API Key Auth" option.
Your API Key validation test is done using your Token.
https://developer.themoviedb.org/reference/authentication-validate-key
If your Token works then your API Key must also work.

If you checked in another way, please let us know which way it was.

Hello TMDB Support ...
I am also receiving this message.
"status_message": "Invalid API key: You must be granted a valid key.",
Please advise. I did take the test above and it failed.
