502 Bad Gateway - Debian 9

Hello,
I am installing Zammad for testing and for possible production.
I encounter a problem that despite my search did not find a solution.

The famous Nginx 502 Bad Gateway error

I understand that we must change the file /etc/nginx/sites-available/zammad.conf by putting the FQDN.
Being local, I put test.local and in the host of my PC, I added @ipServer -> NameServer
Unfortunately, I still have this error that prevents me from launching the Zammad page.

My config:
Debian 9
Source of installation:
https://docs.zammad.org/en/latest/install-debian.html
https://docs.zammad.org/en/latest/install-elasticsearch.html

I tried several reinstallation of my server, the application without result.

/var/log/nginx/zammad.error.log

*2018/07/23 13:33:32 [error] 22490#22490: 5 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.2.4, server: helpdesk.test.lan, request: “GET / HTTP/1.1”, upstream: “http://[::1]:3000/”, host: “test.lan”

Could you help me ?

thank you in advance

  • Used Zammad version: 2.6
  • Used Zammad installation source: (source, package, …) Install on Debian via DEB
  • Operating system: Debian 9.5
  • Browser + version: Chrome 69.0.3497.100 / Firefox 62.0.3

I tested with a CentOS 7 to check and I also have the same problem.
With this procedure: https://docs.zammad.org/en/latest/install-centos.html#change-your-webserver-configuration-non-localhost-connections

I’m doing something wrong?

2018/07/23 13:33:32 [error] 22490#22490: 5 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.2.4, server: helpdesk.test.lan, request: “GET / HTTP/1.1”, upstream: “http://[::1]:3000/

The Zammad-Service doesn’t seem to be running, is not opening the port (for whatever reason) or a firewall on the system is blocking the access to Port 3000.

Please also provide production.log .

Hello,

Thanks for your feedback.
I have not entered any production.log

Zammad looks OK

I have these log in zammad.error.log (sorry I made a mistake to copy paste in my first post)

Zammad needs a lot of things to be running:

The list above doesn’t show elasticsearch that in my case is on another server. Elasticsearch is also a requirement. Have a look at your services.

For me it’s OK, no ?

Hello,

Would you have an idea of ​​why the error ?

What’s the output of netstat -tnlp

Here is the result

Hi,
please check the output of

sudo systemctl status zammad-websocket
sudo systemctl status zammad-web

From your latest output it looks like the websocket server and the zammad app server is not running

Yet the result below shows the opposite right?

What happens when you enter:

curl http://127.0.0.1:3000/
or http://localhost:3000

do you get a valid responde (which I doubt)
If not your service may not be started successfully.

Please restart the service and post the log output here. Full Log, without personal information.
/var/log/zammad/production.log
/var/log/message or /var/log/syslog depending on your setup

Thanks for your help :slight_smile:
I think there is a problem indeed but I do not know how to solve it

Do you know why it’s blocking?
Ports are yet open

This means your Zammad is not running at at all.
Which matches your curl to localhost result

we agree.
I followed the procedure, that’s why I’m asking for help.
Your procedure indicates prerequisites that I followed.
I tested your other procedure on CentOS to check if I had misunderstood steps.
I get the same result.

I’m not a pro but the services zammad, zammad-web and zammad-websocket stupid OK, we saw it above.
What can I do to make it work?

Thank you

From your log:

Oct 26 12:17:05 Zammad zammad-worker-1.service[29386]: PG::ConnectionBad: could not connect to server: No such file or directory

Is your database setup correct? Zammad could not start because it’s missing a database. Maybe your config
/opt/zammad/config/database.yml is not correct

Regards

postgrey seems OK and the file contains that:

It is not running. Like the status message says it has “exited” it should be “active”
It also did not show up in your netstat list. The default port is 5432.
