How to install SSL on Apache2 for Ubuntu 14.04?

I have purchased my certificate from Namecheap, and they gave me .crt and .ca-bundle

I’ve followed this tutorial: https://www.digitalocean.com/community/tutorials/how-to-create-a-ssl-certificate-on-apache-for-ubuntu-14-04

But it doesn’t work, does anyone know why I still can’t access https://mydomain.com?

At this point, I’ve gone through so many tutorials from DigitalOcean whether needed or not because the tech support always give me a tutorial link without knowing what my actual problem is.

Some of the modification I’ve made were from these tutorials: https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-14-04https://www.digitalocean.com/community/tutorials/how-to-create-a-ssl-certificate-on-apache-for-ubuntu-14-04 https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-with-a-free-signed-ssl-certificate-on-a-vps
