Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/webmin.yellowpageskenya.com/fullchain.pem
Your key file has been saved at:
/etc/letsencrypt/live/webmin.yellowpageskenya.com/privkey.pem
Your cert will expire on 2023-01-11. To obtain a new or tweaked
version of this certificate in the future, simply run certbot again
with the "certonly" option. To non-interactively renew all of
your certificates, run "certbot renew"
My web server is (include version):
Apache2
The operating system my web server runs on is (20.0.4):
The version of my client is certbot 0.40.0 no certbot-auto
That's the certificate. It needs the key as well, and probably some other lines too. I linked the Mozilla SSL config generator above, it will tell you everything you need to know a lot better than I can.
