I am guessing that web sockets don’t run on a separate port anymore. I took out nginx and now directly connecting to zeppelin which is running fine on port 8001. I see this error in the chrome browser -
WebSocket connection to 'ws://ec2-197.compute-1.amazonaws.com:8001/ws' failed: Error during WebSocket handshake: Unexpected response code: 403 Any clues anyone?
