Scheduled Refresh Fails but data get refreshed....

Hello all,

When I try and refresh the dataset either manually on the service or through an scheduled refresh I get a fail but the data (and the time of refresh) get updated...

Anybody know why this happens?

In the past I deleted the dataset from the service, re-uploaded it and worked (although all my dashboards had to be remade).

But this happened again and I am still getting the fail even after I tried the above solution.

Could this maybe have something to do with dashboards? Everytime I create them something seems to go wrong...
