HAProxy Not Working With Zammad

[yuljk]

Hi - I'm attempting to get HAProxy working with Zammad. From my understanding the web application listens on port 3000.

I have a HTTPS front for SSL offloading and a HTTP backend (port 3000) for Zammad, however under HAProxy stats I see 'Layer 4 connection problem - connection refused'

Here is my HAProxy config:

acl helpdesk-acl var(txn.txnhost) -m str -i ticket.somedomain.com
use_backend helpdesk_ipvANY if helpdesk-acl

HTTP Zammad Backend:

backend helpdesk_ipvANY
mode http
id 104
log global
http-response set-header Strict-Transport-Security max-age=31536000;
timeout connect 30000
timeout server 30000
retries 3
option httpchk GET /
server server 192.168.5.184:3000 id 122 check inter 1000

The nginx configuration for Zammad has been left untouched, apart from changing the hostname to my external FQDN.

Many thanks

Can you check with a netstat -noa or something like that that the Zammad server is really listening on 192.168.5.184:3000 ? or 0.0.0.0:3000 perhaps.. What happens when you try and visit that http://192.168.5.184:3000 with a regular browser from a computer on the network? Does it connect? i guess not..

Layer 4 connection problem - connection refused is clearly says that port you mention doesn't open or listen. So: or you have firewall issues on your server or app not listen on server IP you are pointing.
