I had done. #93

change LINE_DOMAIN from http to https LINE_DOMAIN = "https://gd2.line.naver.jp"

in client.py disable self._headers['X-Line-Application']=app then in api.py in def login(self):

j = self.get_json(self.LINE_CERTIFICATE_URL)

add: self._headers['X-Line-Application']=app self.transport.setCustomHeaders(self._headers)

but it can not work.
