That is unfortunate but thanks for the answer. Can you point me to some documentation where this is specified? The only hint I got is that from this page
https://docs.microsoft.com/en-us/azure/machine-learning/data-science-virtual-machine/dsvm-samples-and-walkthroughs#access-jupyter
where it says that
>> You can also access Jupyter on Linux editions of the DSVM
remotely from a web browser by visiting https://<Full Domain Name or IP Address of the DSVM>:8000
on Ubuntu.
