Push not working with GIT, while commit is working

I configured GIT in Katalon.
I can do commits without any problem.
When I push a change I get a popup to enter my credentials. When I enter my credentials I get the message ‘not authorized’.

Anyone common with this problem?

1. commits are local thing nothing to do with push
2. are you able to push using git console?

Thanks for your response.
Yes I’m able to do a push. With Git Bash (dos prompt) I can execute a push without problems.

there must be something not configured properly. are you using same auth. method from git bash and Katalon?

It works now.
When I login with the same credentials for GIT and Katalon it works.
