"Blocked Host" error after docker-based install

[TomFrost]

Using the Docker-based install script instructions from the website, I installed MissionKontrol (kuwinda/kuwinda container) using the command:

./auto-install.sh --run --use_https --ssl_cert /path/to/cert.pem --ssl_cert_key /path/to/privkey.pem

And when loading the application in my browser, I get:

Blocked host: my.hostname.net
To allow requests to my.hostname.net, add the following to your environment configuration:
config.hosts << "my.hostname.net"

There doesn't appear to be a way to do this via the script+docker install method.

Edit: Realized after simplifying the install that this isn't specific to SSL or remote. I ran the container with barebones settings and accessed via localhost, and still got the message that localhost is blocked. Did I miss a step? This seems like something everyone would be running into... but that doesn't appear to be the case.
