Error when trying to access user's profile

[TumFlyG]

I have created an application on Spotify Dashboard that converts all my songs from the collection liked songs to a playlist using a programming language Python. Everything was fine untill yesterday, when I encountered the following issue and I do not understand what I should do. Here is the issue:

requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: https://accounts.spotify.com/api/token
During handling of the above exception, another exception occurred:
raise Spotify Oauth Error(
spotipy.oauth2.SpotifyOauthError: error: invalid_grant, error_description: Refresh token revoked

I also tried to create another application, but nothing has changed.

If you are using Spotipy, you can try to delete the .cache file out of the directory you are running the script from. Then you'll need to log in again.
