Can't connect to Redis with default configuration

  File "/srv/www/aleksis/venv/lib/python3.7/site-packages/redis/connection.py", line 643, in on_connect
    auth_response = self.read_response()
  File "/srv/www/aleksis/venv/lib/python3.7/site-packages/redis/connection.py", line 756, in read_response
    raise response
redis.exceptions.AuthenticationWrongNumberOfArgsError: wrong number of arguments for 'auth' command 

Changing the user setting to an empty string fixes the problem:

[redis]
user = ""
