Hello everyone,
Hope you can actually assist me a bit with this.
We have an internal infrastructure with some VMs acting as servers, one of them is OSTicket and we have another one that a Windows Server ADCS to issue certificates for internal services.
I've tried issuing certificates for OSTicket service so we can access it through HTTPS protocol.
After configuring the certificates and issuing the RootCA certificate for our server, I cannot start Apache HTTPD Service...according to the error_log it has something to do with mod_ssl, so I also checked that log file and found:

What is the reason this is happening? Can I delete all of the certificates, and start over?
Would that be enough to make the service start back?
