I'm trying to use the Proget Docker registry as proxy to a docker daemon running on another machine

docker run -d --restart=always -p 5000:5000 --name docker-registry-proxy -v pwd/config.yml:/etc/docker/registry/config.yml registry:2

here is the config.yml
version: 0.1
log:
fields:
service: registry
storage:
cache:
blobdescriptor: inmemory
filesystem:
rootdirectory: /var/lib/registry
http:
addr: :5000
headers:
X-Content-Type-Options: [nosniff]
health:
storagedriver:
enabled: true
interval: 10s
threshold: 3
proxy:
remoteurl: https://ip_of_the_proget:443/
username: api
password: some_password

If i try to get a new image
docker pull nginx for example

I get following error in the registry docker

level=error msg="response completed with error" err.code="manifest unknown" err.detail="unknown tag=latest" err.message="manifest unknown"

Question:
Does the ProGet works as registry docker image proxy ?
