Windows Agent Zertifikatsschlüssel algorithmus wird nicht unterstützt

Hallo zusammen,

ich habe einen neuen Icinga2 aufgesetzt inkl. Director. Nun möchte ich meine Agents verbinden.
Es kommt im Agent folgende Fehlermeldung:
“Failed to receive certificate: Der Zertifikatsschlüsselalgorithmus wird nicht unterstützt.”

Woran kann das liegen? Ich finde im Web leider keinerlei Hilfestellung hierzu.

Infos zur Umgebung:

  • Version used (icinga2 --version): r2.13.4-1
  • Operating System and version: Ubuntu Server 22.04.1 LTS
  • Enabled features (icinga2 feature list): api checker command ido-mysql mainlog notification
  • Icinga Web 2 version and modules (System - About): 2.11.1
  • Config validation (icinga2 daemon -C): Keine Fehler in der Konfiguration

Danke für eure Unterstützung.

Viele Grüße
Giorgio

Anyone who can help on this? I really have no idea for the moment how I can solve this issue. It is not the fist Icinga environment I setup but it is the first time this issue appears.

Thank a lot for every help / hint.

Regards,
Giorgio

Hello there,
your post must have slipped through, else I would have sent a message earlier.
We would like to keep the forum exclusively in English, so I would like to ask you to translate and repost this topic. This would probably also help with finding someone who can help you.

Thanks in advance!

Hello together,

I integrated a new Icinga2 installation including Icinga director. Now I want to add some windows agents to the environment.
When trying to add a new windows agent following error is popping up:
“Failed to receive certificate: Der Zertifikatsschlüsselalgorithmus wird nicht unterstützt.”

What can be the reason for this? I cannot find any information to this error in the internet.

Information to my environment:

  • Version used (icinga2 --version): r2.13.4-1
  • Operating System and version: Ubuntu Server 22.04.1 LTS
  • Enabled features (icinga2 feature list): api checker command ido-mysql mainlog notification
  • Icinga Web 2 version and modules (System - About): 2.11.1
  • Config validation (icinga2 daemon -C): no error in configuration

Thank you in advance.
Giorgio

Hi Gigi,

I have never seen this error before.
But the message is quite clear, though I don’t know where it comes from.

Have you checked the troubleshooting section on certificate issues from the docs and seen if anything there helps identifying the problem?
