I have cloned the repo with https with my username and password as [discussed here][1] in this format:

git clone https://USERNAME:[email protected]/username/reposlug.git

but when I try to push a new branch I get an error:

remote: The requested repository either does not exist or you do not have access. If you believe this repository exists and you have access, make sure you're authenticated.
fatal: unable to access 'https://bitbucket.org/mydomain/myrepo.git/': The requested URL returned error: 403

The password I created had full rights, I even made it again to be sure. I was able to clone the repo ok with the username and password so I have no clue why I cannot push.
