I'm getting the error message, "Authentication Failed. You may not have persmission to access the repository or the repository may have been archived. Open options and verify that you are signed in with an account that has persmission to access this repository".
I'm puzzled because I do have permssion and I'm signed in to the github accoun that i want to push to! I was able to push the first time, but not after that.
Solved! Solved! Go to Solution.
I had 2x this problem also,... solution is to log out from github desktop, remove key (revoke) from https://github.com/settings/applications and log in again, which will generate new key.
