Not responding on Docker 17.06.2-ce

[bizmate]

I have just created a stack on top of the latest 17.06 docker and it had already some naming problems with the volumes due to forward slashes. I created a PR for this on the catalogue. https://github.com/rancher/community-catalog/pull/615

But also I get a

ERR_EMPTY_RESPONSE

When calling my registry UX (portus) on port 5443. I am unfamiliar with portus and I was wondering if you could suggest what I can look for to fix it?

The docker compose i used while PR is reviewed
