I haven't pushed to this repo in a few weeks, but now i can't. I ran into an issue like this before and remedied it by clearing git credentials as i saw in another StackOverflow post. However none of the questions i have found have remedied this issue.
This is a new branch that i'm setting up and trying to push, i'm also up to date on the latest Git as of 6/5/2018, and i don't have 2FA set up on this account as of right now.
Any and all help in fixing this would be greatly appreciated because i can't find a way to fix this at all through their documentation or stack overflow.
