All the websites I host do not work!

Hello,
Since Cloudflare runs on my server only my own website that works, however none of the websites I host work.
I have these kinds of messages on all browsers

    Um, we can not find this site.

    Can not connect to the server at www.esj-football.fr

    If the address is correct, here are three other things you can try to do:

         Try again later.
         Check your network connection.
         If you are connected through a firewall, check that Firefox has permission to access the web.

and

    This site is inaccessible www.wantete.fr took too long to answer.
    Try the suggestions below:

    Check the connection
    Check the proxy and the firewall
    Run Windows Network Diagnostics
    ERR_CONNECTION_TIMED_OUT

In short the DNS are not solved. Is there anyone to help me?
