Hi all,

I was trying to find something similar but this question does not seem to be answered before, sorry if I didnt find it.

I am deploying with docker machine a haproxy configuration that includes letsencrypt for two subdomains. I got these errors:

haproxy |<7>haproxy-systemd-wrapper: executing /usr/local/sbin/haproxy -p /run/haproxy.pid -f /usr/local/etc/haproxy/haproxy.cfg -Ds

This is the configuration (Sorry for the formatting):

chroot /jail

backend apptest_server

What I am missing?
Thanks in advance for your support!
HAProxy is great!!!
