Acutally I have no idea what I did, but adding a line to the login function of downloader.py fixed this problem for me.

## downloader.py

121     def login(self):
122         logging.info('Login...') 
123         driver = self.driver
124         driver.get(self.actions_class.login_url)
125         driver.delete_all_cookies()
126         add_cookies(driver, self.cookies)
 +          driver.get(self.actions_class.login_url)
128         logging.info('Login finished...')

@chierinyan fwiw this didn't fix it for me so it may have been something else on your end
