When I tried to open a newly created workspace hrml-001 from the Machine Learning Studio, it failed with the following error:
Error loading workspace

I also found there was another workspace hrml01, which had already been deleted from the Azure Portal but still existing in the Machine Learning Studio. The issue happened since I deleted the hrml01. Not sure if it was the cause of the problem.
