We are unable to access this connected repository on GitHub The authorization key is not valid, or the account used to connect to GitHub doesn't have access to the repository. Try disconnecting the repository above and then reconnect. That is the error I got when trying to connect my private GitHub repo to Heroku.
I've tried doing everything like making it public, or making a new repository, but it just won't work.
I don't have any code to show, since this is a Heroku problem, not a problem with the code.
I don't know what to do.
