RedHat 8.6/OEL 8.6: OCS Agent 2.9.3 comm error

Hi folks

I've installed the OCS inventory agent from source (2.9.3) but in my ocs log there is a communication issue everyday. If i run the ocsinventory --force command, it actually works and communicates all the info to the OCS server. 

I read in another thread that the OCS agent should version should never be older than the server version, my server is version is 2.5 could this be the problem?

here is my OCS log which shows OCS running from my cron.daily:

Hi,

Client version must not be greater than server version => [Wed Jul 13 06:05:02 2022][error] Cannot establish communication : 400 Bad Request. You can't use agent 2.9.3 with server 2.5. 

Update your server to 2.10 to use 2.9.3 agents otherwise stay with 2.5 and use 2.5 agents or less.

Regards

Frank
