Thanks for posting here. Based on your topic, I presume your Master repository is failing to update itself and you have received a notification on the same. Since it is a fail from McAfeeHTTP, I would like to confirm that there is no issue from your Network when the server tries to reach our update Server.
May I know what you see when you try to access "update.nai.com/Products/CommonUpdater" from the ePO Server's browser?
