Icinga2 not listening on port 5665 on Debian 11 (Bullseye)

Icinga 2
1

Hello,
i’ve noticed that the current version of icinga2 it not correctly working on Debian11 (Bullsyeye). I icinga2 as an agent on a Proxmox VE 7 Server (based on Debian11) and the Icinga-Master was not able to connect to the agent on port 5665. It turned out that icinga was not listened on port 5665 or even another port (i didn’t changed anything in the configs). This was reproducable on another Proxmox VE7 host and even on a fresh installed/updated Debian 11 VM:

When you restart the icinga2 service it also hangs/freezes a few seconds or even minutes until it starts again.

Hi & welcome to the icinga community,

According to your logs API is no enabled. You can check this with

icinga2 feature list

to enable it use

icinga2 feature enable api

This will only work when your certificates are fine.

Hello and thanks alot!
i thought icinga is always listening on this port, after i run the kickstart script (director) it enabled the api feature and now its listening on 5665 :slight_smile:
