New Discourse Installation: Emoji's not appearing

Hi there,

I briefly searched through but could not find something similar to this that had a fix. I just installed Discourse on a DigitalOcean droplet and I’ve noticed that the emojis and user profile images (default system assigned images) does not appear.

I’m currently running Discourse version: v2.2.0.beta7 +141

Here is a screenshot of the issue:

Any help or suggestions would be greatly appreciated.

What is the exact url to the missing image? This should give you clues.
