Google Cloud Platform: Cannot get https (SSL) working on Wordpress Instance

Question

I'm using Apache/2.2.22 (Debian) on Google Compute Engine with a Wordpress Install (click-to-deploy).

I'm trying to setup an SSL certificate (https) for the Wordpress install. I've created a static IP, a private key, a CSR and have uploaded SSL & intermediate crt files (from freeSSL.com) to etc/apache2/ssl (with the private key) and given this folder root:root permission.

I've followed https://www.digitalocean.com/community/tutorials/how-to-create-a-ssl-certificate-on-apache-for-debian-7 and updated default-ssl config file as instructed (updating pathnames to .crt and .key files, ServerName and ServerAdmin).

I ran a configtest (got syntax OK), enabled default-ssl and rebooted apache. When I visit https://domain or https://ip-address, I get a "This Webpage is Unavailable" error (ERR_CONNECTION_CLOSED). The wordpress install still loads ok on http.

The SSL checker at https://www.digicert.com/help/ gives me a "no certificates found" error, although the certificates are there.

Answer 1

Here's what worked for me;

First attempt to enable HTTPS with the checkbox in the Compute | Compute Engine | VM Instances config settings. Should this fail with an error message you can add a firewall rule directly...

On the Compute | Compute Engine | Networks page, select the 'default' network. Then under 'Firewall rules' click 'Add a new rule'. Use the following settings;

Name: allow-https
IP Range: 0.0.0.0/0
Allowed Protocol/Ports: tcp:443
Target tags: http-server

All of the above is assuming that you have exhausted all the other apache configuration options (ports.conf, Virtual Hosts etc).
