ActiveSync probe ActiveSyncCTPProbe is failing on server

Hi

We have the following error on a 2013 CAS that I cant seem to find any details on (see below).

CAS is part of a migration from EX2010 and sits behind TMG2010. All systems are working, CAS is passing traffic through to 2010 CAS.

Any help much appreciated.
