Cause and Solution
Check whether there are network or Internet connectivity issues connecting to the Azure blob storage. You can use curl to ping the URL of the blob storage.
One cause of the issue may be that this is a Java certificate trust issue. If you overwrite the Java trust store, using the -D flagss), the Connector will not trust the Azure IoT Hub and Storage Account SSL certificates (any public CAs).
