Do you have a firewall between CM an VG? Is it a new install or it was working before ?

Well the VG is in Germany and the CM in France.. VG connects via MPLS network to the cluster.. I inherited this issue.. been a couple of months in my current role .. the history was that back in November when it started the
QoS was modified from af31 to af41... they clamined it worked ..until now..
