Hi @NCherbib 


installation package is including necessary URL's for agent communication. You agent could not registered somehow to XDR management console and could get license, Thats why its normal to see protection status is not green. 

I believe, You should have logs about API accesses. kind of reject, timeout etc. 


My recommendations is checking again network layer (fw, proxy etc) and dns resolutions. on the network layer, there should not be any SSL interception for palo alto network urls. 

if there is no problem on the network layer, could share full trapsd.log?

@NCherbib it seems like the endpoint never managed to connect to Cortex XDR. What happens when you run 'cytool reconnect force'?
You might want to open a Support ticket in parallel with the Agent Support logs for an investigation.
