Let's Encrypt Ubuntu

All my website with SSL encrytion were working fine. I have deleted my Floating IP as I don't need it, and now I have only one website working with the LE SSL encryption.

So I have relaunch the command :
/opt/letsencrypt/letsencrypt-auto --apache --renew-by-default -d -d -d certonly

But the LE SSL encryption still doesn't work for

I don't know what to do. When I try to go to it tells me with Firefox Error Code : SSLERRORBADCERTDOMAIN .com uses an invalid security certificate. The certificate is available only for the domains:,,

Indeed my LE SSL encryption is working for

What can I do ? What do I have to check ?
Thanks for your help.

Found !

I had to change the apache config file /etc/apache2/sites-available/

    <IfModule mod_ssl.c>
    <VirtualHost *:443>


    <IfModule mod_ssl.c>
    <VirtualHost XXX.XXX.XXX.XXX:443>

Where XXX.XXX.XXX.XXX is my public ip address.

The question is, why was it working like that before deleting my Digital Ocean Floating IP and by the way, changing my server public IP address ?

Anyway, it's working fine now :D
