Why doesn't python instagram work, with authorization problems?

Question

Python

A similar question was asked, but I have a different problem. Registered the application, received client_id, client_secret, access_token.

api = InstagramAPI(client_id=client_id, access_token=access_token, client_secret=client_secret)
popular_media = api.media_popular(count=20)
for media in popular_media:
    print media.images['standard_resolution'].url

We get an error:

InstagramClientError at /citys/
(404) Unable to parse response, not valid JSON.

We try another request and get an error

api.tag(tag_name='sun')
(400) OAuthPermissionsException-This request requires scope=public_content, 
but this access token is not authorized with this scope. The user must re-authorize 
your application with scope=public_content to be granted this permissions.

It turns out that the problem is in the token, and I need to get it again, but why, if it is always the same!

Answer 1

Perhaps because Instagram closed its API?
