Following is the configuration for the proxy (IPs in logs modified for privacy):

   global
   log /dev/log local0
   log /dev/log local1 notice
   chroot /var/lib/haproxy
   #stats timeout 30s
   #user haproxy
   #group haproxy
   daemon

defaults
   log global
   mode tcp
   option tcplog
   option dontlognull
   option logasap
   timeout connect 50000
   timeout client 50000
   timeout server 50000

listen stats
        maxconn 1000000
        bind 0.0.0.0:8081
        stats enable
        mode http
        stats realm Haproxy\ Statistics  # Title text for popup window
        stats uri /stats  # Stats URI
        stats auth stats:stats  # Authentication credentials

frontend local
        bind *:1900
        bind *:443
        tcp-request connection expect-proxy layer4 if { src -f /etc/haproxy/proxies.lst }
        mode tcp
        default_backend nodes

backend backnodes
        mode tcp
        balance roundrobin
        source 0.0.0.0 usesrc clientip
        server one 10.10.10.10:1900 check

proxies.lst has a single line 1.1.1.1

Clients are unable to connect, if I check logs I see the following line,

Jun 11 10:46:39 udasddg0 haproxy[16981]: 1.1.1.1:51000 [11/Jun/2018:10:43:19.855] local backnodes/one 1/-1/+200005 +0 sC 31/31/30/30/3 0/0

From what I understand:

sC means server timed out and client reset the connection after that
also looks like Tc= -1 which means that the actual server did not respond to the proxy.

If I follow tcp stream in wireshark on the proxy server I see that we are receiving the proxy info:

PROXY TCP4 2.2.2.2 3.3.3.3 53889 1900

Not sure why the connections are failing. Any suggestions would be appreciated.
