title: Wireshark does not capture python POST request
body: <p>I have a python script which triggers a http POST request using standard libraries. I'm trying to view and debug the requests content by capturing in wireshark.</p>
  
  <p>The request is sucesfull because I recieve the correct server response. 
  In wireshark I listen on all available interfaces but cannot find the request. </p>
  
  <p>I have also tried some filtering options like http filter but the request was still not found. </p>
  
  <p>I have Ubuntu installed and the server host is not localhost</p>
  
  <p>How can I find the request?</p>
