Alerts authentification failure ::1

Hello,

I'm using Dell OME 2.1.0.2635 to monitore Dell PowerEdge servers (T410, T420, T430, T610) with Dell OMSA 8.2 installed.

I'm getting a lot of Authentification Failure alerts like the following :

When i try to ignore this type of alert, i've got a popup Window which said that it can't link the device for this alert :

Is there any way to know which device is sending this alert ? (or force ignore this alert)

Thank you for your help.

Best Regards,

Samy Girard
