General: Pick your list of vHosts.
Perhaps merge the list: Every combination of port and domain name should be unique.
If non-www and www use the same vHost, check, if the vHost has one domain name as ServerName, the other as ServerAlias.
Then create certificates:
certbot -d e-synergisud.fr -d www.e-synergisud.fr
certbot -d dev.e-synergisud.fr
so every vHost has it's own certificate.
In the end, the certificate with all domain names should not longer used.
Currently, you use it ( e-synergisud.fr - Make your website better - DNS, redirects, mixed content, certificates ):
CN=e-synergisud.fr
