DNS Error Occurred

Hey everyone. When I try to view my website, it now doesn’t work. I have parked my domain correctly and used the correct DNS Settings as it worked for around an hour, and without me changing anything now it says DNS Error. Can anyone help?

For anyone wondering this is the website: www.chilliforums.com

You domain is not pointing to 000webhost nameservers. Currently your nameservers are ns01.domaincontrol.com and ns02.domaincontrol.com whichs is not 000webhost nameservers
