--auth does not work with Python 3

[frakman1]

I ran the same droopy.py with Python 2 then Python 3.
--auth works as expected with Python 2.
With Python 3.6.4 on Win 7 -64bit, I get this error:

>python droopy.py --auth test:test

Exception happened during processing of request from ('127.0.0.1', 53806)
