But with other branches everything works great. Am I doing something wrong?

EDIT: Remote repo was not bare, more info here

Answer 1

You must be trying to push a new commit to replace an existing commit already push ("history rewritten")

You need to do a git push --force, or select a similar option (if supported) in the git push wizard dialog of NetBeans.
And that suppose that the "push --force" is authorized on the remote repo (which isn't always the case).
If other have already pulled from the remote repo, rewriting its history is generally not a good idea.
