I parked my domain sth.com to my website sth.000webhostapp .
Can you provide a screenshot your sites load on both addresses you provided me.
I see no suspended domain like you’ve said?
Make sure to give your browser cache a flush and even your computer DNS cache
Has to be a DNS issue, that page is not related to 000webhost.com
What operating system do you run?
Can you give this a try?
