I am trying to run a Python module using a Jupyter Notebook on Azure HDInsight, but I continue to get the following error message: A connection to the notebook server could not be established. The notebook will continue trying to reconnect, but until it does, you will NOT be able to run code. Check your network connection or notebook server configuration.
I have an Azure subscription, created a cluster, created a storage blob, and have created a Jupyter Notebook. I am successfully logged into the cluster, so I am not sure why I cannot connect to the notebook. Any insight into this problem would be hugely appreciated.
