Error 500 in container_registry

Hi,

I followed this guide https://github.com/sameersbn/docker-gitlab/blob/master/docs/container_registry.md to activate gitlab docker registry. But I am getting a 500 Error when I click on container-registry. I found an identical issue the fix was to upgrade redis to redis:4.0.9-1 but I am already using redis:4.0.9-2. Here is my yml file. I hope someone can help me because I don't know what to do anymore.

`version: '2'

this is the log what comes from registry:

Start with docs/container_registry.md and the supplied Compose configuration, then inspect the registry log shown in the issue. Compare the GitLab and registry settings, including the certificate and token-auth paths. Done means clicking container-registry no longer returns HTTP 500 and the registry can authenticate successfully.
