title: unable to configure grafana with graphite
body: <p>I am using Nginx to serve both graphite and grafana (they are all running on the same server - not my desktop).  I am able to access graphite via Nginx.  However, grafana cannot seem to connect to graphite (error: Graphite HTTP Request Error).  I have copied the nginx config below for grafana - any ideas on fixing this will be appreciated. 
  The request URL that fails in the browser is this (accessible if I access it directly in the browser): </p>
  
  <pre><code>**http://xxx.xxx.xxx.xxx:8080/render**
  </code></pre>
  
  <p><strong>Nginx default</strong></p>
  
  <pre><code>server { 
          listen 85;  ##listen [::]:85; #ipv6only=on;
          server_name grafana;
          root /home/xxxx/grafana-1.5.3/;
          index index.html index.htm;
          ##logging per server
          access_log /var/log/nginx/grafana/access.log;
          error_log /var/log/nginx/grafana/error.log;
  
         location / {
         ##  root /home/xxxx/grafana-1.5.3/;
         }
  }
  </code></pre>
  
  <p><strong>config.js URL for graphite (in grafana)</strong></p>
  
  <pre><code>graphiteUrl: "http://xxx.xxx.xxx.xxx:8080"
  </code></pre>
  
  <p><strong>Edit</strong>
  Graphite does not need authentication for access from grafana.  Also, I am using grafana v1.5.3</p>
