HAProxy not running stats socket

I installed haproxy from aur in Arch Linux and modified the config file a bit:

global
    maxconn     20000
    log         127.0.0.1 local0
    user        haproxy
    stats socket /run/haproxy/haproxy.sock mode 660 level admin
    stats timeout 30s
    chroot      /usr/share/haproxy
    pidfile     /run/haproxy.pid
    daemon

defaults
    mode    http
    stats   enable
    stats   uri /stats
    stats   realm Haproxy\ Statistics

frontend www-http
    bind 127.0.0.1:80
    default_backend www-backend

backend www-backend
    mode        http
    balance     roundrobin
    timeout     connect 5s
    timeout     server  30s
    timeout     queue   30s
    server  app1 127.0.0.1:5001 check
    server  app2 127.0.0.1:5002 check

I have made sure that the directory /run/haproxy exists and has permissions for the user haproxy to write to it:

 ツ ls -al /run/haproxy
total 0
drwxr-xr-x  2 haproxy root  40 May 13 21:37 .
drwxr-xr-x 27 root    root 720 May 13 22:00 ..

When I launch haproxy using systemctl start haproxy.service, it loads fine. I can even go to the /stats page and view stats, however, socat reports the following error:

ツ sudo socat unix-connect:/run/haproxy/haproxy.sock stdio
2016/05/13 22:04:11 socat[24202] E connect(5, AF=1 "/run/haproxy/haproxy.sock", 27): No such file or directory

I am at wits end and not able to understand what is happening. This is what I get from journalctl -xe:

Basically, no errors/warnings or not even so much as an indication about the stats socket. Others who have faced a problem with the stats socket fail to get haproxy started. In my case, it starts up fine, but the socket just isn't creating.
