Cannot find my wordpress page

Beside my original homepage "https://peters-homepage.000webhostapp.com/"
some time ago I started with a second WEB page using Wordpress. After changing the
original homepage to the new members area, I’m not able to access or to
find the second WEB page which was accessable before under "http://wpheu.peter_heuss.net23.net/"
Pls help

That is because subdomains are not available anymore. Let me contact an admin to see about this, because this is the first I’ve heard of migration data loss that is related to subdomains.
