you can delete the host afterwards…

If I add “Icingaweb2” to the url you provided: http://192.168.10.180/icingaweb2/director/self-service/register-host
I can register the host fine actually:

Seems this may be a bug. I’m running into the same issue. Did you resolve this?

It still persists if I try to autoinstall everything with the script. However, if I change the script and remove the install commands and insert a skip wizard:

& $ScriptFile `
    -ModuleDirectory 'C:\Program Files\WindowsPowerShell\Modules\' `
    -SkipWizard;

and afterwards manually use the IMC (typing “icinga;” in PS) to set it up, everything works fine for me so far! In the IMC I use “connect from this PC” instead of the “Director Self Service API”.

@Johannes @akellar
What are the settings in the “Icinga Agent and zone settings” section of your hosttemplates?

Johannes · December 6, 2023, 3:21pm

Hey @moreamazingnick
I have this setting currently. Am I lacking something?

moreamazingnick · December 6, 2023, 3:43pm

change it to establish connection no…

Johannes · December 7, 2023, 6:51am

The error persist with that change, when trying to automate the whole installation:

did you remove the host from icinga director before trying again?

Johannes · December 7, 2023, 11:03am

I did, yes. And deployed changes of course.

edit: php file located in /usr/share/icingaweb2/modules/director/application/controllers

@Johannes @moreamazingnick found this issue on their github. Implementing the fix PHP fixed my issue without having to make any changes to the script from the host template in the director.

Self Service API not working with PHP 8.2.7

## Expected Behavior Self service should work ## Current Behavior Icinga Fo…r Windows fails using the Self Service API. ## Possible Solution This code Block produces deprecated output and prevents parsing of the json. https://github.com/Icinga/icingaweb2-module-director/blob/aa31b37fd184228d3397c512ae8fc175f2d82d39/application/controllers/SelfServiceController.php#L403-L411 ``` Deprecated: strlen(): Passing null to parameter #1 ($string) of type string is deprecated in /usr/share/icingaweb2/modules/director/application/controllers/SelfServiceController.php on line 407 \n ``` I fixed it in my installation with checking if the $value is null but my php knowledge is not the best so i do not know if there is a better way. ```php protected function addStringSettingsToParams(Settings $settings, array $keys, array &$params) { foreach ($keys as $key) { $value = $settings->get("self-service/$key"); if ($value != null) { if (strlen($value)) { $params[$key] = $value; } } } } ``` ## Steps to Reproduce (for bugs) Install icinga director on Debian 12 bookworm with php 8.2.7 and try to add a host using the self service api.

@akellar That did the trick! Thanks so much

I have the same issue. I tried all suggestions from this thread, but it’s still not working.

This is working btw.

Edit:
If I use the deprecated Icinga 2 Agent from https://github.com/Icinga/icinga2-powershell-module it’s working fine. That’s the Agent I have actually running on my Windows servers.
