title: Can't start Cloudera Manager, site not reachable
body: <p>I have a small cluster with three nodes on my home server for learning purpose.</p>
  
  <p>It was working fine after it was initially set up.</p>
  
  <p>I haven't used it for a month and today when I try to use it, I found Cloudera Manager GUI cannot be accessed, I checked the network between the 3 nodes are good, they can ping to each other.</p>
  
  <p>On master node where CM is installed, I tried service cloudera-scm-server start, it shows me [OK] in green; when I check the status it shows the following info:</p>
  
  <pre><code>[root@pocnnr1n1 ~]# service cloudera-scm-server status -l
  ● cloudera-scm-server.service - LSB: Cloudera SCM Server

  </code></pre>
  
  <p>So, is the Cloudera Manager service started or stopped?</p>
  
  <p>When I try to access CM through GUI, it shows below in chrome:</p>

  <p>Can anyone help me to fix it? Thank you very much.</p>
