Routing domains, always goes to default

I’ve been goggling and looking for guides and tried piecing this together with lo luck whatsoever. What I need to do is direct web traffic to different servers depending on the domain (for now)… I’m using the latest HAProxy (1.7.9 running on an Ubuntu machine (virtual) and my router directs all traffic for port 80 to it.
I’ve been following what guides I could find to the best of my understanding and I finally have the service at least start without failure, but once running it seems it completely ignores all my hostmapping and just sends everything to the default backend.
I have 3 webservers running on 3 different machines with their own static IPs (2 Apache and 1 IIS) and this is the config I’ve come up with.

global
log /dev/log local0
log /dev/log local1 notice
chroot /var/lib/haproxy
stats socket /run/haproxy/admin.sock mode 660 level admin
stats timeout 30s
user haproxy
group haproxy
daemon
maxconn 256

Please someone help me figure this out and point me in the right direction, I would be immensely grateful!
