I’m unable to pull image via Dependency Proxy. I login to proxy with : docker login my.gitlab.com
then with below command pull docker image
my.gitlab.com:443/groups/mygroup/dependency_proxy/containers/busybox:latest
but get this error: Error response from daemon: error parsing HTTP 404 response body: unexpected end of JSON input: ""
GitLab service run with docker and the ports 80,443 are published.
Try using my.gitlab.com:443/mygroup/dependency_proxy/containers/busybox:latest
This solved problem for me.
