Dear Community
I try to get an SSL Labs A rating for my CentOS8 Apache-server.
I'am sure it has to do with my lack of understanding the crypto-policies configuration, can anybody give me an advice where i am wrong?
My understanding is that the configuration in the pmod-file will override the ssl.conf values if PROFILE=SYSTEM is active.
