  <p>Tried installing the packages suggested in <a href="https://stackoverflow.com/questions/29099404/ssl-insecureplatform-error-when-using-requests-package?noredirect=1&amp;lq=1">SSL InsecurePlatform error when using Requests package</a> getting the same warning issues.</p>
  
  <p>I cannot upgrade the python version due to some constraints. Any other way to resolve the issue?</p>
