So it looks like that error is a result of Azure responding back with this error code:
I'm don't know all the scenarios that Azure would report that error, but my first guess would be that something is violating the naming conventions.
Yet, you mentioned that you were able to use the Create Container and Query Container successfully. Is it possible that there's some copy-paste artifacts in the either the Storage Account Name or Destination Container inputs?
The VI for creating the container works fine. Only if a file is to be loaded into this container (Example test.txt), then comes this error. We kept to the rule of names.The connection to the Azure will be established.
The next problem: we have all VI stopped, but every hour data is transferred to the cloud. Is anything programmed to transfer the data in the background?
