FortiSIEM with certificate from Microsoft AD CS

Hello,

Since I did the integration of an SSL certificate signed by a Microsoft ADCS certificate authority. I have SSL errors in the phoenix.log related to the phMonitorSupervisor. And in the Cloud Health section, the supervisor status is critical.

phMonitorSupervisor[1519691]: [PH_HTTP_CLIENT_CURL_ERROR]:[eventSeverity]=PHL_ERROR,[procName]=phMonitorSupervisor,[fileName]=phHttpClient.cpp,[lineNumber]=882,[infoURL]=h_t_tps://*.*.*.*:443/phoenix/rest/sync/task?custId=1&agentId=1&time=1677772602,[phLogDetail]=curl error (60) Peer certificate cannot be authenticated with given CA certificates for method: GET

On the other hand, I have a valid certificate when I connect in the WEBUI of FortiSIEM.

In the FortiSiem documentation, it describes the procedure to add a signed certificate. But I have an impression that it is only for CA authorities like Entrust, etc.

So, should we add the root CA of ADCS in the OS certificates (rocky Linux)?

Thanks for your help
