Scheduled refresh timeout 10-20min after start time

Hi,

We have two scheduled refreshes per day and every now and then refresh timeout occurs due to the same table (approx once or twice a week). I have not found any reason why it happens only sometimes.

Weirdest detail at least for me is that the failure time is approx 10-20min after the scheduled start. How is it possible to runout after 1min? In addition, when I refresh this dataset in desktop it takes time max 15min and has never failed. Size is 100-200mb.
