I've not personally had any issues with systemd which I know doesn't mean there isn't any... However, on closer inspection, it gets started through a wrapper "haproxy-systemd-wrapper" for me :
[Unit] Description=HAProxy Load Balancer After=network.target [Service] ExecStartPre=/usr/local/sbin/haproxy -f /etc/haproxy/haproxy.cfg -c -q ExecStart=/usr/local/sbin/haproxy-systemd-wrapper -f /etc/haproxy/haproxy.cfg -$ ExecReload=/bin/kill -USR2 $MAINPID KillMode=mixed Restart=always [Install] WantedBy=multi-user.target So definitely check if you are using that wrapper or not if systemd is being used. Otherwise, my feeling is that for whatever reason you cannot access the socket previously created due to permissions... I mean I can get the same error trying to start HAproxy as an unprivileged user who cannot write to the file/directory.
