How to configure HAProxy to "proxy" two domain names to different ports in localhost - tomcat8

Question

I have one server containing FE app and BE for it. FE listens port 80 and BE is deployed to Tomcat listening default port 8080. HAProxy is used to listen port 443 / handle ssl. Proxying to FE / port 80 works fine, but not to BE / Tomcat listening port 8080. Here's the configuration I'm using:
global
log /dev/log local0
log /dev/log local1 notice
chroot /var/lib/haproxy
maxconn 3072
tune.ssl.default-dh-param 2048
stats socket /run/haproxy/admin.sock mode 660 level admin
stats timeout 30s
user haproxy
group haproxy
daemon

cookie node1
Tomcat works fine using ip address directly, so that's not the case. So help is needed for the host_be / becluster.
