Might be the DNS you're using. If you have no special settings then your IP provider resolves names (doe sthe DNS) for you.
Noticed the same using 9.9.9.9 a while back and had to manually edit /etc/hosts to have the correct IP address found in there.
I'm currently running with 94.103.94.73 for
8kun.top
sys.8kun.top
media.8kun.top
etc.
If the DNS is the problem in your case, you can use for example https://intodns.com/ to determine currently working IP addresses
(pic) is from qresear.ch, from back when all anons had to set it manually.
But remember to make a backup copy of your hosts file before editing, so you can revert it to default, in case something goes wrong.
