Can't See Domain only Index

So I have set up my Linode and configured Apache et al but when I try to view either of my domains, I only see the index. You can see what I mean by looking here.

I'm trying to get to the url marcmanley.dev.

As you can see, I have two domains currently associated with this virtual host. When I go to imammarc.com, it works as it should. It's only with marcmanley.dev. that it's not behaving correctly.

Perhaps a setting I missed? I followed the steps as dictated here: https://www.linode.com/docs/websites/hosting-a-website-ubuntu-18-04/

Running Ubuntu 20.04

Thanks in advance.
