Hello.
Those “script kiddy install server” are not a good thing for several reasons witch are not the focus here.
You d better switch to a fully managed server with ssh and root access.
Concerning your problem, have your ever reach the web landing page.
This look like those possible problem:
- the hostname conf is faulty or the DNS is pointing to some strange DNS like serverid.provider.tld.
- your server use some kind of reverse proxy…
- your server conf (apache2 or nginx) is faulty.
In any of those case, your softaculous provider should be able to help you.
