OpenManage Essentials Critical Error - vrrpTrapAuthFailure

Hi All

I have taken over the running of our OpenManage Essentials Server system (version 2.4.0.930), and there is a worrying amount of critical errors withing the Home Portal. This error source is a vrrpTrapAuthFailure within the Network Category. The description of the event is: "A packet has been received from a router whose authentication key or authentication type conflicts with this router's authentication key or authentication type". This error occurs every few seconds.

The device in question is our router's IP address.

Anyone has any experiences with this error, and a possible resolution?
