A week ago everything it was normal with my app deployment on Heroku using my Github repository.
Now, HerokuApp doesn't have access to my github and everytime i try to connect it shows me this error:
"Couldn't connect to GitHub Error: remote was closed, authorization was denied, or an authentication message otherwise not received before the window closed."
Does anybody know what happened?
Yep. This is a known issue happening at Heroku.
