Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: mail.pronostics-courses.fr
I ran this command: certbot certonly --standalone mail.pronostics-courses.fr
It produced this output: succeded
My web server is (include version): Nginx
The operating system my web server runs on is (include version): Debian 10
My hosting provider, if applicable, is: OVH recent VPS
I can login to a root shell on my machine (yes or no, or I don't know): yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): no
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you're using Certbot): last version
I succeded while getting a web server certificate for both : pronostics-courses.fr and .com , with and without www. and postfixadmin.
Then, I got another certificate for mail.pronostics-courses.fr.
Wonder if I should revoke the mail certif, then add a mail certificate to the web server certificate.
Thank you very much for your help.
