Unable to connect to redis server deployed on Amazon ec2 on port 6379

I have set up a redis server on AWS ec2 instance following https://medium.com/@andrewcbass/install-redis-v3-2-on-aws-ec2-instance-93259d40a3ce

I am running a python script on another ec2 instance

import redis

try:
    conn = redis.Redis(host=<private ip address>,port=6379, db=1)
    user = {"Name":"Pradeep", "Company":"SCTL", "Address":"Mumbai", "Location":"RCP"}
    conn.hmset("pythonDict", user)
    conn.hgetall("pythonDict")
except Exception as e:
    print(e)

In the security groups of the redis server, i have allowed inbound traffic on port 6379

While running the above script, i am getting following error:

Error 111 connecting to 172.31.22.71:6379. Connection refused.

I have already tried changing the bind value in conf file, as suggested by a few answers to similar questions on stack overflow, but it didn't work

Assuming your other instance is within the same subnet as the Redis instance, my suggestion would be to review a couple of things:

  1. Make sure among your security group inbound rules, you have your Redis port set up for the subnet, like:

    6379 (REDIS)    172.31.16.0/20

  2. From within your Redis configuration (e.g. /etc/redis/redis.conf), in case this hasn't been done, either bind the server to the private IP (bind 172.31.22.71) or simply comment out any existing localhost binding, then restart Redis.
