Python application stuck on is_ready function

[gabrielbastoos]

I've an application developed in Python and i'm using hx711.py source code to import the HX711 class, after importing, i'm getting stuck on return GPIO.input(self.DOUT) == 0 . I tried running the example.py code and also had the same error: MYPATH/hx711py/hx711.py", line 51, in is_ready return GPIO.input(self.DOUT) == 0

Is this a hardware error or a software error? I checked HX711 module board VCC and it was receiving 4.85V, that's ok, but I think DOUT is on level HIGH.
