HPE OneView for Microsoft System Center Rabit MQ Client setup ERROR

[jan_nevaril]

Hello,

I have installed HPE OneView for Microsoft System Center version 10.3, imported management packs

We are running SCOM 2019, 2 management servers, HPE Event Manager installed on both management servers

Added appliance via SCOM without any problems, objects were discovered.

There are no alerts generated in SCOM, 

I have found the following error in HPE OneView Management, all needed FWs enabled tpc80,443,5671
I tried to install a different version but getting still the same error

[8/25/2023 9:20:16 AM PID=8168] (InternalError) Event: Internal Error.
Error occured during Rabit MQ Client setup. Appliance:10.xx.xx.xx  Appliance 7.10.0

Any suggestions?

Hello,

We suspect it to be a certificate issue. It is required for the internal functioning of the RabbitMQ message bus server within HPE OneView. 
This root CA is internally used to sign the RabbitMQ server and RabbitMQ client certificate. The internal root CA and the RabbitMQ client certificate must be imported to any external client using AMQP to communicate with HPE OneView. 
The internal root CA or the RabbitMQ certificates are not displayed in the Manage Certificates screen, but are available using REST APIs.

Cheers...
