I wanted to post this as a heads up. I just went to manually connect a clients custom domain to a site and came across the auto connect custom domain feature for GoDaddy. I was using Chrome and the dialog box kept timing out and giving me a failed connection message. I switched over to Safari and it worked almost instantly on the first try.
Just a heads up incase you come across the same issue!
*also, not sure if the should be listed as a solution or not, just wanted to spread the info!
