Committing to a repository - not authorized

I created a new repository and I’m trying to push my local project to it. I can pull the skeleton project that was initially created but now matter what I do, it won’t authenticate I get the error message "not authorized.

Using Eclipse IDE with the git plugin.

Its my project and I’m the admin, but can’t make this work. I’ve spent 2 days on this already and need help. I tried creating a PAT, I’ve tried everything I can think of.
