@Reception123 It should be okay now! I got the site admin to enable that feature and now it should be directed correctly. Thanks for being so patient again.

It would appear I've found the issue! I tried doing that before, but got an error saying "CNAME records on dynamic dns domains are currently restricted, contact an admin for assistance to have it enabled," so I just assumed it was wrong.

The above image shows the screen I'm looking at when trying to point the CName (I'm using FreeDNS). What exactly do I have to do to actually point it to mw-lb.miraheze.org?

Have I completed it correctly now? Also, sorry for the change, but I updated the custom domain request to tla.awiki.org.
