Automatic set up being blocked. Possible IP blacklist

Hi guys! Moving onto subscription, and very excited with all WP DEV can do! Alas there's clearly a setting somewhere in thesingersportal.com which is blocking WP IP address? I've whitelisted the IP address and activated a "whitelist," function in WP SPAM SHIELD, but trying to automatically update via syncing with WP DEV site is still being blocked or not working with the first stage of the SECURITY install? Could you help please? I want to make sure the install is completely ok and working? Sincerely Jezz
