Hi everyone,
I'm quite new with Haproxy and I have a weird behavior with external check..
here is my config file :
global
log /dev/log local0
log /dev/log local1 notice
chroot /var/lib/haproxy
stats socket /run/haproxy/admin.sock mode 660 level admin
stats timeout 30s
user haproxy
group haproxy
daemon

And yet I get a 503 and in my logs I got this :
...: Server web-backend/web1 is DOWN, reason: External check error, code:
255, check duration: 5ms. 1 active and 0 backup servers left. 0 sessions
active, 0 requeued, 0 remaining in queue.

...: backend web-backend has no server available!
...: backend web-backend has no server available!
How could the check */bin/true* fail and return 255 ?
I'm running the latest stable version (1.6.5)
If someone have an idea of what I'm doing wrong please heelp ! ^^
Bye,
