Harness community Edition || Quickstart || Pipeline not getting deployed

Hello Team,
I am closely trying to follow this official documentation of Harness Community Edition Deployment and after following each and every step identically When i try to Run it, it just keeps on loading, without any change happening , when I checked the developer console , there was just one fetch request happening continuously and pipeline was not getting updated at all and finally after sometime the ng-manager becomes unhealthy and all of the setup stops :(, This is the point where I am stuck since so long now, Can anyone please help me out here ?
Thanks and Kind Regards,
