title: Cannot access Apache Zeppelin server from browser
body: <p>I have a virtual machine running Ubuntu 16.04 and I have downloaded Apache Zeppelin 0.7.0. The problem that I am facing is that when I try to start the Zeppelin server using <em>bin/zeppelin-daemon.sh start</em> it says ok  but I cannot access it from the browser(using the default localhost:8080). If I run <em>bin/zeppelin-daemon.sh status</em> it says that the server is already running.
  Also, I tried to start the server using <em>bin/zeppelin.sh</em> and this time some information is displayed in the terminal but with no effect. </p>
  
  <p>Any idea will be highly appreciated. </p>
  
  <p>Thank you!</p>
