Set up Ubuntu Apache2 SSL using .pem and .key from Cloudflare

问题

I am using Cloudflare to set up a secure connection on Ubuntu 20 using Apache2. I used their Origin Server wizard to generate the following files:

example.com.pem (Origin Certificate)

example.com.key file (Private key)

I gave them the extensions suggested by Cloudflare.

I ran this:

 sudo a2enmod ssl
 sudo systemctl restart apache2

This is my setup:

<VirtualHost *:443>
    ....
    SSLEngine on
    SSLCertificateFile /path/example.com.pem
    SSLCertificateKeyFile /path/example.com.key

The non-secure site works fine (I haven't pointed it to the secure yet), but I still get error 525 (SSL handshake failed) when I try to access the secure site. (I got a website down error before running the sudo a2enmod ssl command)

I tried to see if it was set up ok:

apachectl configtest

It just says "Syntax OK"

(Edit: I removed the wrong stuff I tried - which I now know is wrong - to simplify the question.)
