Artifactory based docker registry showing 404 error

I am trying to setup my first Artifactory based docker registry and I am hitting wall one after another.

So, my artifactory installation is docker-compose based and running on a Ubuntu 20.04.4 LTS VM (c36l83serv01.simnetaus.local). Here is a view of my docker and postgres running:

Docker is running on local network 192.168.0.168

I have another VM (c36l83linr01.simnetaus.local) which is hosting nginx (install using apt) nginx version 1.18.0

here is my nginx reverse proxy setting, which was copied from Artifactory generated stub:

        }
    }
}

My artifactory is configured for nginx as well:

I have created docker-local, docker-remote and docker (virtual) repository;

I could login to the registry from my windows command line:

However it won't allow me to push:

If I use port in the url as suggested the repo settings, I get following error:

Anyone have any clue? WHat am I doing wrong? Any suggestion or help would be highly appreciated.

Thanks.
