title: Cntlm is not properly routing
body: <p>I have setup my config file like so (omitting the username, domain and password fields):</p>
  
  <pre><code>Username user
  Domain domain
  Proxy           127.0.0.1:3128
  NoProxy         localhost, 127.0.0.*, 10.*, 192.168.*
  Listen          127.0.0.1:3128
  </code></pre>
  
  <p>I have added the PassLM, PassNT and PassNTLMMv2 lines, after having created a hash.</p>
  
  <p>I run it like so:
      sudo cntlm -v -c /etc/cntlm.conf</p>
  
  <p>Now, I am attempting to use curl to hit an api endpoint through the proxy server like so:</p>
  
  <pre><code>curl https://url -k --proxy-ntlm -u user:password --proxy 127.0.0.1:3128
  </code></pre>
  
  <p>However, I receive an error each time:
  curl: (56) Received HTTP code 502 from proxy after CONNECT</p>
  
  <p>I can tell that the proxy is being accessed, because cntlm spits out a long string of data after I issue the curl.</p>
  
  <p>Not sure what I am doing wrong here, any help would be much appreciated!</p>
