Domain unavailable to access

Hi guys,
I was having trouble earlier with this plugin, and learned that my httpd.conf file on my new host was incorrectly configured. It took a few weeks to figure that out. Now I'd like to try this plugin again, but I'm unable to successfully map kowalskis.ca to test.mywriting.network because the domain appears unavailable. I can't seem to figure out why. I have an A record set at GoDaddy using @ for the host, and the IP address is correct. Can you help? Support access has been granted. Thanks!
