I found the problem this is because I have many vhost I remove all vhost expt the original vhost create by letencrypt and now it is ok

Yep, these duplicated definitions

@michael10fr

default server www.monexpertinfo.com (/etc/apache2/sites-enabled/000-default.conf:1)
port 80 namevhost www.monexpertinfo.com (/etc/apache2/sites-enabled/000-default.conf:1)
port 80 namevhost www.kippaperso.com (/etc/apache2/sites-enabled/kippaperso.com.conf:1)
alias kippaperso.com
port 80 namevhost www.monexpertinfo.com (/etc/apache2/sites-enabled/monexpertinfo.com.conf:1)
alias monexpertinfo.com

are bad.

Recheck it with apachectl -S, every combination port + domain name should be unique.
