Can't push or edit repository for which I am admin

[mcordiner]

I'm going back to a repository for the first time since I made it public about a year ago. I just wanted to edit a text file, but the edit icons are all greyed out.  So I went to the teminal and made the edits there, but upon pushing I get 

Password for 'https://<user>@bitbucket.org':

remote: You may not have access to this repository or it no longer exists in this workspace. If you think this repository exists and you have access, make sure you are authenticated.

fatal: Authentication failed for 'https://bitbucket.org/mcordiner/sublimed.git/'

I tried making an access token, and used that as the password, but after running 

git config user.email <string>@bots.bitbucket.org

...I still get the same authentication failure. It's like I'm locked out from editing my own repo. I have checked and there are no branch restrictions in place. I confirm that I can log in to bitbucket and modify the repository settings, but cannot edit the files.

Help!
