Error 503

[stephenamsel]

Hi,

I followed the instructions given in the Readme as well as I could and have now successfully added and removed servers in the back-end, but there appears to be a traffic-routing problem. I am using DOProxy with a pair of servers set up following the steps described here:
https://www.digitalocean.com/community/tutorials/how-to-create-a-high-availability-setup-with-heartbeat-and-floating-ips-on-ubuntu-14-04

I used an image from a server which runs a fully functional website, receiving HTTP traffic and responding normally, to create a back-end server but when I went to the Floating IP address of the (primary) balancer and got a 503 (no server available) error. Is there some additional configuration necessary that I missed?
