Infos:

  • Used Zammad version: 6.4.1
  • Used Zammad installation type: (source, package, docker-compose, …) Docker-compose
  • Operating system: Ubuntu Server 22.04
  • Browser + version: Chrome 132.0.6834.159 (Official Build) (64-bit)

Expected behavior:

  • I switched from Nginx Proxy Manager to Zoraxy.
  • Before the switch, I was able to test the email notification and send out emails.

Actual behavior:

  • After the switch from Nginx Proxy Manager to Zoraxy, I get the following errors
Connection could not be established with host "mail.example.com:587": stream_socket_client(): Unable to connect to mail.example.com:587 (Connection refused)

I have other docker apps behind Zoraxy and I don’t have this issue. There is are only two apps I do, this one and invoiceninja. Exact same error.

Steps to reproduce the behavior:

  • Test sending email.

Hi @Dvalin21. And what should we do now? :thinking:

Sorry to say I have no answer for your issue.

But maybe you want to share how you successfully configured Zammad with Zoraxy? I, too, moved away from Nginx-PM and so far can’t manage both at the same time:

  • either configure Zammad as http → links are bad and mobile view/websockets won’t work
  • or configure Zammad as https → “CSFR Token verification error” whenever I try to log in

Thanks for sharing!

The Proxy server has nothing to do with this.
The stack is simply not able to talk to the mail server in question.

In the past this sometimes was connected to ipv6 not working.
