I am first trying this Databricks after completing the basic training and unfortunately I have run many tests on the community version for students and every connection fails. The Databricks runtime cannot resolve external hostnames. requests.get() fails with NameResolutionError, %sh ping google.com reports "Temporary failure in name resolution", and %sh nslookup google.com returns server can't find google.com: and showing REFUSED. The same domains resolve correctly from my local machine. This appears to be a workspace or compute networking/DNS issue rather than an application or API problem. If you can kindly fix the issues to begin with that would be the main purpose of using databricks for analytics. Can anyone help me solve this problem? 
Thank you.
