First off, good to see you switched to the official docker container.
I have a small problem however. I added the docker however i'm getting the following error:

It does give me a button to click to add it to the trusted domains but that doesn't work.
I'm sorry if i'm being stupid but, i add the container, leave everything default and get nothing but,

I get this with both the Owncloud containers listed in community applications.
