Ansible-pull ask always to put credentials such as Username and Password

Hi all,

I have setup a GIT Repository and I need to use now via ansible-pull the correct username and passwort to pull the data out of it.
When using the correct credentials it keeps asking me again and again for the credentials. But it does not pull the Playbooks at the end.
So I am stuck in a infinity loop here.

I tested the same with the git-client and tried to pull the data. This was working fine and I could get the code without any issue.
Anybody who was facing the same issues?
Thanks.
