If you have network connection Ok. And traffic is not dropped by FW, and bare in mind that if you are using proxies you should have them properly configured at the agent, try to:
cytool reconnect force 

Having the protection mode enabled should not be a problem for connecting to the tenant

Hi @NCherbib 

Could you check trapsd.log to know more about problem? 

You can find trapsd.log from agent console or ;

windows = c:\programdata\cyvera\logs

Mac OS X 10.10 and OSX 10.11= /var/log/traps/
macOS 10.12 and later releases= View logs from the Console application in /Library/Logs/PaloAltoNetworks/Cortex XDR/.

that's what i got:

Hi NCherbib,

To enable access to Cortex XDR components, you must allow access to various Palo Alto Networks resources. Can you confirm if access is allowed from the server in question to the specific resources relevant to your deployment? You can reference the document linked below to find what specific resources are required for your region.

Resources Required to Enable Access to Cortex XDR

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.

@NCherbib you can try to uninstall the current version, and install with downgrade version. example you can install using version 7.5.0

It's work for me. If you want upgrade to latest version you can upgrade from the console.
