Hello,
This is a common issue with new accounts. Clear your browser cache and flush your DNS at regular intervals. It can take up to 48 hours for this error to pass. If you're still experiencing the issue in 48 hours, please let us know by replying to this ticket.
Until then, as I said, clear your cache and flush your DNS until it starts working. I can see your site with no issues, so it probably won't be too long.
Thanks.
