Hi @WilliamFoisseau-


Have these machines ever been able to communicate with the Cortex XDR tenant?  If not, have the certs in step 3 of this document been added to the certificate store on the affected server?

Can anyone help me with the location to download the root certs required and the location to add these .crt files to? I have got the certs and added them to the ca-bundle.crt file in /etc/ssl/certs and have restarted but it does not work, unfortunately.
