Please note, that in options are unsupported regions/ instances combination, I was unable to detect or filter out unsupported instances/region combination at the time of development. Please try Hong Kong for example or any Chinesse datacenter.
Also it may work for other Datacenters - with some instances. This problem will be fixed soon, because all Cloud Tools gets updated in few weeks.
Thanks for understanding.
