Unable to Reach app from Specified URL

I am new to Haproxy. I intend to do a reverse proxy using Haproxy. My setup is as follows

I have two Haproxy Servers with keepalived installed for HA, and then I have my applications hosted on several web servers with several applications running on them using Apache virtual hosting

I want to expose a particular web application over the internet <example.com>. I can successfully Curl that URL from the haproxy servers when i do curl <example.com>. I set the needed parameters in the host file of the haproxy servers

But when i map that URL to a public IP of the Haproxy Server, I get redirected to a different application been hosted on that same web server. Any idea what i have done wrong. My configuration is shared below

  log local0
  log local1 notice
  chroot /var/lib/haproxy
  stats socket /var/haproxy/admin.sock mode 660 level admin

backend example_server
  balance roundrobin
  server web_srv
  log global

You mention that you get redirected to another application. Are you saying that something different loads or that the haproxy instance is sending you to a different location?

Try running curl http:/// from your machine and that should hit the haproxy instance and then be passed along to port 80 on your backend server.


This has been fixed. My bindings (80,443) seemed to be the issue. When i changed to *:80 and *:443, all was fine
