Answer 1

what it is not able to talk to? Hardware and recovery or status recovery endpoint? is this the only machine giving problem or there are other machines as well giving you trouble?
are you able to browse the URL from this bad machine? Do this- go to HKLM\Software\Policies\Microsoft\FVE\MDOPBitLockerManagement 
there will be two URLs one to escrow the recovery password and other for client reporting. make sure you are able to browse through the URL from IE, you should something see like "meta data publishing is disabled". 
if it works then you will need to check the logs from helpdesk website,
