I’ve installed certbot as per the instructions on the certbot site, I’m running CentOS 7 and Apache.
When I try to issue a certificate, it says it has been successfully generated. My browser then shows that it’s a self-signed certificate that has been implemented.
I’ve tried running “sudo certbot --server https://acme-v01.api.letsencrypt.org/directory” and re-issuing the certificate via that, but that also didn’t work. I’ve restarted the server and apache numerous times. I’ve also tried changing the SSLCertificateFile to the fullchain.pem file.
This was on a completely fresh server.
