Linux agent not connecting to server

Hi everybody,

i have problems communication with an inventory linux agent 2.8.1 rhel 8.3 to my ocs server 2.8.1 RHEL 7.9 :

"cannot establish communication : 500 can't connect to "ocs server":443"

Local inventory works fine.

Have more linux-agent 2.8 rhel 7 and no problem but it's the first time client linux agent RHEL 8 …

thanks by advance

PS : je peux parler français si cela peut vous convenir.
