Bitlocker Save key to Azure AD Required Network urls/Ports list

Hi Experts,

I got some errors on the device when I try to save Bitlocker key to Azure AD. I am sure on this I think Network firewall team is blocking the required ports, I would like to know what are the base required ports to communicate correctly with Azure AD as these devices are azure AD joined.

  1. What are the required ports or URLS / IP whitelist for Azure AD join ?
  2. List of Ports or URL / IP list for storing the Bitlocker Key in Azure AD.

Note:- all these devices are behind the Corporate Firewall.

Thank you for your time in reading this.

Appreciate your response.!!
