We have a small site and local APs are connecting over an MPLS WAN line to the controllers in different location.
Since the MPLS line was down on last friday, AP's could not connect anymore to the controller:

I was thinking maybe the iSP did some changes on their side but they didnt confirmed. Its weird that APs cannot build anymore tunnels with the controller.
However, I can ping the APs from the controller.
