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?

Hi,

 

A just install the root certificat on all device

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.

This will be Linux distro-specific.  Ubuntu will look like:

 

  1. To add: 
    1. Copy your CA to ls /usr/local/share/ca-certificates/
    2. Use command: sudo cp foo.crt /usr/local/share/ca-certificates/foo.crt
    3. Update the CA store: sudo update-ca-certificates
  2. To remove:
    1. Remove your CA: rm /usr/local/share/ca-certificates/foo.crt
    2. Update the CA store: sudo update-ca-certificates --fresh
