Using Sonatype Nexus docker proxy

  docker, java, nexus, nginx, proxy

I have a Sonatype Nexus deployed under (it’s behind an nginx proxy).

I created a docker registry and docker proxy and added them to one docker group "company-docker-group". The proxy is set to mirror and also has the foreign layer caching option checked.

I have a http connector set for port 8092 but at this moment I do not have access to change the nginx configuration so that I can access that port directly. I noticed that there is an URL in the docker group defined as

Am I able to access the group via this url? I am able to docker login into this url but then when I try
docker pull
then I get this error:

Error response from daemon: manifest for not found: manifest unknown: manifest unknown

Can I only access the image via or is there a way to use the docker group URL?
