Although I thought the same thing, “give it a few hours/days it will have to propagate the right information,” nothing has changed. I started the process of transferring who the register of the domain is (from GoDaddy to Dreamhost). I’m having a feeling I didn’t need to go that far, but that’s something I’ve been waiting to do anyway, but I don’t know why I still can’t access the subdomain.
The subdomain has an installation of Drupal on it, and I can’t proceed with the install until I access it. Any suggestions?
