Blocked host

I've been trying to get Feedbin up and running for the last day behind Traefik and am getting stuck firing up the feedbin-web instance.

I keep getting the following error on the webpage:
```
Blocked host: feedbin.DOMAIN.TLD
To allow requests to feedbin.DOMAIN.TLD, add the following to your environment configuration:

config.hosts << "feedbin.DOMAIN.TLD"
```
I checked the environment variable, and it's correctly set to feedbin.domain.tld in the container. I also tried editing https://github.com/feedbin/feedbin/blob/master/config/environments/production.rb#L3 and restarting the container without any luck.
