title: Android Retrofit post request doesn't reach server
body: <p>I have very strange issue. Post request doesn't reach server. I have <strong>HttpInterceptorLogger</strong></p>
  
  <p>, so i see logs(see below). Other post requests work correctly, but they didn't send json:</p>
  
  <p>Also checked this request via browser and it worked fine. No idea where could be an issue. Please help to fix it.</p>
  
  <p>I have request:</p>
  
  <pre><code>@POST(LEAD_SET)
  Observable&lt;ResponsePojo&lt;LeadsPostPackage&gt;&gt; setFullLead(@Body RequestPojo&lt;LeadsPostPackage&gt; leadsRequestPojoRequestPojo)
  </code></pre>
  
  <p>And this is response:</p>
