    Hi

    Are your AVD Session Hosts protected by NSG and/or Firewall? Has there been any changes made that would cause the Hosts to not be able to communicate with either Azure AD or the AVD Registration services? The Domain failures suggest that it cannot contact Azure AD.

    Article below gives details of what is required:

    Hope this helps,

    Thanks
