I have installed a free Comodo SSL certificate to shared hosting for my domain. Totally 5 .crt files. However they have no effect. I cannot open my domain.

When I type https: //example .com Firefox says "Unable to connect, Firefox can't establish a connection to the server at, etc." – ilhan Mar 23 '11 at 18:50
The HTTPS port (port 443) is closed. You need to tell Apache to listen on the HTTPS port. – Stefan Lasiewski Mar 23 '11 at 19:02
Also note issued a warning regarding Comodo issuing fraudulent SSL certificates for some very high profile domains today (,, which is a very serious mistake. Many browsers issued updates to block these certificates. I wonder if these updates are blocking some other Certificates from Comodo SSL as well. – Stefan Lasiewski Mar 23 '11 at 19:46
This question appears to be off-topic because it concerns the use of shared web hosting by end users or resellers, rather than the administration of web hosting. – Jenny D Jun 28 '13 at 9:39

You need to set apache to listen on port 443 (in ports.conf or httpd.conf), you need at least create a virtualserver for port 443 and a config file pointing to the certificate. Tell us if you did that and what error do you have so we can try to help you solving your problem better.

Sounds like he's using CPannel, and depending on how it's configured, all of these directions might be wrong for his host... – Chris S Mar 23 '11 at 18:09
@Chris S - You're right. I just wanted to give him a start on where to look if he was lost but it is true this is only valid for "normal" apache config. – laurent Mar 23 '11 at 18:27
