        I am unable to get actual of IP of client in backend server after trying:
        Option Forwardfor
        Transparent Client IP

        These are different ways to get the client IP on the backend.

        ForwardFor inserts the "X-Forwarded-For" header with the origin client IP into the request to the backend.
        You have to configure your backend server to utilize it.

        In transparent mode HAproxy sends requests with the source of the origin client IP to the backend.
        But this is a pretty hack. I'd recommend to rather use ForwardFor.

        But you have to state the ForwardFor option in the frontend, not in the backend. On the frontend settings page there is a checkbox to enable it.

        Also I'm wondering, why you frontends are listening on the loopback address. Did you forward the incoming traffic to it?

          @viragomann Hi! Thanks for the response.
          I tried configurations on the actual server , e.g; nginx, and turned on x-forwarder header from there, and it worked.
          I have a simple setup, Listening on WAN:443 and then forwarding to server.
          If you have any suggestions , do let me know.
          I appreciate your support.
          Thanks again.

            So did you see the client IP in the log now? If not, what do you see in the X-Forwarded-For column?

              @viragomann It is working. Just need to configure NGINX for header.
              But i am facing speed issue, simple webpage is taking 30+ seconds to load.
              It's on aws , i dont know what to do now.

                Does this also happen if you bypass HAproxy?
                Simply add a NAT port forwarding rule on WAN to the backend server for testing.
