Hello,I’m encountering an issue with the Centreon API (v24.10) when retrieving downtimes.Sometimes, without explanation, API returns an empty response even though a downtime is correctly created and active at the moment of the request. {    "result": [],    "meta": {        "page": 1,        "limit": 10,        "total": 0    }}Could you let me know why the API returns this empty result while a downtime is currently active?Is there any known behavior, specific condition, or configuration that could cause this intermittent response? Note that this is the same response we receive when there is no downtime in progress.Therefore, this does not allow us to detect the error. Thank you for your help.

Bonjour,Connaissez-vous un moyen de superviser un FortiAP avec Centreon ?. Merci d’avance pour votre aide.

Hi, I have an issue with centreon_fortinet_fortigate_restapi.pl. If I try to get license info I get error: UNKNOWN: Cannot decode response (add --debug option to display returned content) Issue comes from the fact that there is letter Ü in output as company name. That messes the output up.I tried different options in the commandline, but at least to me only fix seems to be, is to add UTF-8 encoding to plugin. Or am I missing something or is there some magical hack I can use?NB! It not possible to change the company name not to have that letter Ü in it.
