I have OS CentOS Linux release 7.6.1810 (Core), Apache/2.4.6 (CentOS), Redmine v3.4.6. My site works nice with http, but I want add https support to it. But when I try use https it has endless loading in my browser and then error: This site can’t be reached took too long to respond. I checked my open ports with:
sudo netstat -tulnp
I can see here:
Also I checked it with:
sudo firewall-cmd --list-all
My iptables.service not is inactive (dead). I thought that problem was in SELinux, I tried set setenforce to 0, but it did not improve the situation, so I returned setenforce to 1. I test my httpd config - no errors only: WARNING: PassengerRoot cannot occur within section Syntax OK
I set LogLevel debug in my httpd.conf. But I don't have any error in my logs, moreover as I see on logs with ssl everything is all right:

Here is my .conf for my site:

So problem not in SELinux, ports are open, no errors in logs.
Updated It's not about Apache or Ningh or Redmine, even on a simple standard page, https does not work.
