We're also having the same issue. When I tried to create a task on the web console, it sits there and doesn't do anything.
If I tried to do a manual update from the device, it comes up with "online content is available" (albeit I can ping the web console from the client and vice versa and has internet connectivity).
Was there an update bug that's causing this? Right now I have 10 devices that are sitting as "in danger" while waiting for an update since yesterday.
Thanks!
