Why can't I connect my GitHub repo to Heroku?

Question

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.

Answer 1

As on date 15 April 2022, there is security issue reported on github.

In action of the same, Heroku will not be reconnecting to GitHub till uncertain duration.

Action over the incident is reported on Heroku.
