Listener issues

[etc3p]

After several hours of the server listening for new connections, it is not possible to initiate new communication with the C2, the listener must be restarted

@etc3p @mhaskar you can fix it using a WSGI server such as Tornado or Genvent to run the Flask app,
e.g.

from gevent.pywsgi import WSGIServer
http_server = WSGIServer(('0.0.0.0', port), app, log=None, keyfile=key_path, certfile=cert_path)
http_server.serve_forever()
