I am not sure where to begin.
Background: I had a working system, new, I tried to fumble and change domain name from mail.example.com to just example.com. All services worked, DNS, etc.
My changes broke the system.
So I did all as a clean install, hostname as srv.example.com and mail domain as example.com.
Now, DNS doesn't resolve, and more importantly, neither roundcube nor iredadmin open, even with https://ip_addresses/mail or https://ip_addresses/iredadmin. I tested by turning off firewalld, fail2ban, etc. Nothing.
Please point me in the correct direction before I reinstall again.
