connect to x.x.x.1 port 8000: Connection refused

Hi,
Thanks for this great job!

I am trying the demo 'whoami', and haproxy works fine. I was able to see backend container id.

But when I deployed my own services on one backend server x.x.x.2

• Container 2600516615c7 from Image service1 exposed port 0.0.0.0:8080->5001/tcp
• Container a6fc817cbca3 from Image service2 exposed port 0.0.0.0:443->5000/tcp
  Same containers are running on another backend server x.x.x.3
• Container 814d49616255 from Image service1 exposed port 0.0.0.0:8080->5001/tcp
• Container 31eb936f2e59 from Image service1 exposed port 0.0.0.0:8080->5001/tcp

docker-discover is deployed on server x.x.x.1

But when call service1 api from address x.x.x.1:8080, I got

connect to x.x.x.1 port 8080: Connection refused

I curl etcd for key 'backends/service1', it showed me 3 sub nodes 'backends/service1/2600516615c7',
'backends/service2/814d49616255', 'backends/service1/port'

And for haproxy config, I see

listen service1
    bind *:5001

    server 814d49616255 x.x.x.2:8080 check inter 2s rise 3 fall 2
    server 2600516615c7 x.x.x.3:8080 check inter 2s rise 3 fall 2
