Thanks for posting. Did you recently change your DNS for the domain? That error indicates it is pointing to the wrong IP address, you will need to change your domain's A record to your hosting account's IP address. Hope that helps!
Thanks for replying. I haven't changed anything in quite some time. This just popped up out of the blue. I followed the link you shared, but my A listing doesn't offer a pen icon for editing, so I created a new one. Now there are two. Will one overwrite the other?
No, an extra A record will cause intermittent failures to find the site. If there is no "pen" icon for editing, we are guessing that you have a forward in place for the domain. Are you forwarding it to another, outside hosting plan? If not, you will need to cancel the forwarding command, which will allow you to have only the one IP address you need on the domain (to your hosting plan with us).
