Nothing happens when I hit the "start training" button

I’m using the cloud version of deep learning studio, but when I go to the training tab and hit the “start training” button it changes to “stop training” and a message of “connected to compute server” but nothing happens! No graphs, no samples per second. It is strange because yesterday I successfully trained the same model and the graphs and all the info updated almost instantly. If I train a sample project everything works fine. Any suggestions?

It might be server issue at that time. Did you try training any other model?
