Hi, I have the same issue.
The site was working since few days ago now it's down.
If I check with the hostdomain (coropolifonicovalsile.000webhostapp.com) the site is up and fine working.
I've checked the nameservers (ns01.000webhost.com and ns02.000webhost.com) on the domain provider, iwantmyname, and they are the right ones. They say that on their side everething is working.
The domain is www.coropolifonicovalsile.it.
on Mydomains the pointing seems working, it's labelled as parked, as you can see below. What can I do?
