Dataflow stopped refreshing - No errors - still scheduled

[Syndicate_Admin]

I have a dataflow that has fro no reason stopped refreshing since the 5th November. Refresh history shows it has successfully completed fine 6 times a day before this, but suddenly afterf 5th has not tried to refresh. I can not manually refresh the dataflow either as the refresh button does nothing. The dataflow is scheduled to refresh and this is all still active but when the time to refresh comes it just doesnt trigger. It shows no error messages and doesnt notify me of any issues or reasons why. Help!

Yes, I've experienced exactly this myself in the past.

I think opening the Dataflow to edit it, saving, and choosing to run a refresh when the popup prompts it clears out the cobwebs and gets it going as normal again.
