Today hundreds of my endpoints started reporting that they were out of date in Sophos Central. I'm seeing "Download of WindowsCloudNextGen failed from server http:∕∕dci.sophosupd.com." in the events in Central. The SophosUpdate.log file shows the following:2019-12-09T22:05:41.410Z [ 2528:21248] [v6.1.356.0] ERROR [E53591] Stale update source: stale customer file: previously lastModified 2019-12-05T11:04:57Z, attempted to sync customer file with lastModified 2019-11-14T17:25:59Z
When I go to dci.sophosupd.com/index.html I get "Connection Successful"
Our license is up to date, and I can get to the site that is referenced in the event viewer and the log file. Any ideas?
