Gitlab Registry error

Looking way to debug my problem with Gitlab Registry. In my setup of Gitlab Registry was disabled. After I have enabled it, I have menu option but get error 500 Docker Connection Error. There is link to docs, bit it don’t help me, because I don’t have any symbols in project or group name. If I’m trying to connect with docker cli I got next error

docker login

Error response from daemon: login attempt to failed with status: 400 Bad Request

It is ce edition, Omnibus installation.

Part of my config:

external_url ''
registry_external_url ''
letsencrypt['enable'] = true
