Host not found

When I connect to, I got host not fond issue.
Please see my attached pic, thanks a lot.
There's no picture, but the link is working.

(Didn't you get an email recently about an update in your site and an unavailability of a couple of hours? Maybe it was that.)

No, I didn`t get that email , it`s still not working today.
Hello Eric

From what I've gathered, your personal was stopped due to lack of activity on saturday, but you've started it again on sunday. If you're still unable to connect using the hostname, it's possible that is due to some DNS cache on your network, or PC.

I've confirmed that the personal is working in perfect order, so I ask you to flush the DNS cache and attempt again.
