Hi, i'm trying to access some api calls with the python HTSPClient:

With this code I get a response:

>>> htsp = HTSPClient((hostname, 9982))
>>> msg = htsp.hello()
>>> htsp.send('api', {'path': 'status/inputs'})
>>> htsp.recv()
{'noaccess': 1}

But with authentication it returns nothing and TVH hangs up and needs to be restarted:

>>> htsp = HTSPClient((hostname, 9982))
>>> msg = htsp.hello()
>>> htsp.authenticate(username, password)
>>> htsp.send('api', {'path': 'status/inputs'})
>>> htsp.recv()

All other methods described in Wiki/Htsp works as expected.
