That domain doesn't exist on either server. Are your sure that's the domain of your account? What is your Heliohost username? That's quite strange. I can access my cpanel and I'm pretty sure that's my domain. Yes, that's me. I've tried that hostname, but it doesn't connect. I think I'll wait until tomorrow to see if it will work. I changed the dns about 4 hours ago, so maybe it just needs more time.
