Apache not working on AWS Linux after reboot - 301 Response code

I figured out the issue. When an AWS instance is rebooted, the DNS address changes. As I am using Wordpress, I need to update the siteurl and home url in the MySQL Database for the wordpress site to the new DNS address.

In the pictures below for example localhost should be replaced with the DNS address of the instance. When the instance reboots, this will need to be replaced again with the new DNS address and so on, every time the instance reboots. Really I should have used a static DNS address to save me the pain of this issue :)
