Haproxy in front of containers....more!

So, I have progressed a little with my former issue although things still not working.

To review…I am using port forwarding for various ports to an haproxy server installed on an LXD container.
I also have a container LPC1 with nginx serving pages.

Then I have the following simple frontend:

frontend www_http

    bind *:80 #bind to port 80        
 # it matches if the http host: field mentions any of the hostnames (after the '-i').
    acl host_LPC1 hdr(host) -i lpc1.streamingworld.us
 
# Redirect the connection to the proper server container, depending on the match.
    use_backend cont_LPC1  if host_LPC1

backend cont_LPC1
balance leastconn
# We set the X-Client-IP HTTP header. This is useful if we want the web server to know the real client IP.
http-request set-header X-Client-IP %[src]
# This backend, named here “LPC1”, directs to container “LPC1.lxd”.
server LPC1 LPC1.lxd:80 check

This appears to work as I can display the index.html. Now inside the index.html, I have an iFrame with the src= port 3000 of the same container (LPC1.lxd), so here is what I thought would work for the haproxy:

frontend play
bind *:3000
acl url_static hdr(host) -i lpc1.streamingworld.us/embed/0x35e01199f8137077346fdd476191f1967a52bdb5
use_backend static if url_static

backend static
balance leastconn
#http-request set-header X-Client-IP %[src]
server LPC1play LPC1.lxd:3000 check

I am not sure of either front or backend configurations?

When I run sudo haproxy -f /etc/haproxy/haproxy.cfg -c
Configuration file is valid

But when I restart haproxy, I get:

First I’m not sure why I am seeing double outputs?
But worse, why the connection refused?

Your help us much appreciated!
