I've got a django project using django-redis 3.8.0 to connect to an aws instance of redis. However, I receive ConnectionError: Error 111 connecting to None:6379. Connection refused. when trying to connect. If I ssh into my ec2 and use redis-py from the shell, I am able to read and write from the cache just fine, so I don't believe it's a security policy issue.
Ok, figured it out. What I needed to do was prefix my location with redis://. This is specific to the django-redis library and how it parses the location url. That explains why when I manually set up a StrictRedis connection using the python redis library I was able to connect.
