DFU Mode on every flash from the cloud IDE

Everytime I upload new code from the WEB IDE, my Spark Core does all the common flashes and then starts in DFU after it restarts… I have to re-flash locally to get it to work again. But I can’t flash from the cloud. Everytime it enters DFU Mode!! Any ideas?

Tried factory reset, flashing with DFU-UTIL the latest firmware… Deep Update… No Avail!
