Hi!
I am having the authentication error as well, but I made the mistake of trying to fix it before coming to the community to look for help, and ended up removing my site’s repo in my local machine to clone it again.
When I tried to clone it, however, I’m being asked the credentials to my site, and it doesn’t accept any combination (my account’s password or an auth token I generated for it):
arthr@charlie Sites % git clone git@github.com:arthrfrts/vulcana.git
