title: ERROR blpapi_platformtransporttcp.cpp:671 - Connection issue in R
body: <p>Currently following instructions from <code>rblpapi-intro.Rmd</code> (version date: 2015-08-13) I am wondering why:</p>
  
  <pre><code>library(Rblpapi)
  blpConnect()
  </code></pre>
  
  <p>returns: </p>
  
  <pre><code>17FEB2016_14:27:17.296 7432:8884 ERROR  
  blpapi_platformtransporttcp.cpp:671 blpapi.session.transporttcp.{3}.
  &lt;localhost:8194&gt; Connection failed 
  17FEB2016_14:27:17.296 7432:8884 WARN blpapi_platformcontroller.cpp:371 
  blpapi.session.platformcontroller.{3} Platform: 0 failed 1 consecutive  
  connect attempts, stopped trying to reconnect. 
  Error: Failed to start session.
  </code></pre>
  
  <p>given the below default values:</p>
  
  <pre><code>ip: 127.0.0.1
  port: 8194
  </code></pre>
  
  <p>Factually, there is nothing wrong with those values as I've used them in <code>Matlab</code> using <code>con=blp(port,ip2,time)</code> and the connection succeeds perfectly.</p>
  
  <p><strong>EDIT</strong>:</p>
  
  <p>The below function has finally worked! a bit <code>weird</code>, as I override the default ip value from <code>blpConnect()</code> by the same value.</p>
  
  <pre><code>blpConnect(host = getOption("blpHost", "127.0.0.1"),
             port = getOption("blpPort", 8194L), default = TRUE)
  </code></pre>
  
  <p>Thus it looks like <code>blpConnect()</code> did'nt pointed to the default <code>ip</code> and port values for some reasons.</p>
