I just installed my new letsencrypt certificate on my pache server on centos.. Apache version is Apache/2.4.6 (CentOS)
My configuration si like below:
But when I check on ssllabs I get chain incomplete. Notice that I generated the certificate on another server where certbot is installed.
That is an
apache specific configuration issue.
SSLCertificateFile accepts only one certificate, not a chain. That must be the leaf certificate. You have to use the
SSLCertificateChainFile statement in addition too, and that must be a file containing the intermediate signing certificate(s).
Apache version 2.4.6.
