Problem with container registry

Hi everyone!
I installed gitlab-ee by docker image, its working all right. Then i tried to configure container registry, did everything with ssl certificate, and im getting here v2/_catalog this:

{"errors":[{"code":"UNAUTHORIZED","message":"authentication required","detail":[{"Type":"registry","Class":"","Name":"catalog","Action":"*"}]}]}

When i try to use docker login it asks login and password but then im getting
Error response from daemon: Get "": received unexpected HTTP status: 503 Service Unavailable

I tried everything but cant fix it, can you please help me?
