Hi! I'm not able to connect with "heroku redis" on django

Question

I've followed all the steps in the following video:

https://www.youtube.com/watch?v=fvYo6LBZUh8&t=166s

However, I'm not able to connect with "heroku redis", I am using celery to implement periodic tasks. The error is the following:

[2021-04-02 22:00:05,622: ERROR/MainProcess] consumer: Cannot connect to redis://:**@ec2-54-160-13-161.compute-1.amazonaws.com:12880//: Error while reading from socket: (10054, 'Se ha forzado la interrupción de una conexión existente por el host remoto', None, 10054, None).

So, any idea of what could be happening would be great. ¡Thank you so much!

in my case, it was working fine for some 2 3 weeks. But today it is showing this error. – Lepidus

@RahulHindocha Heroku keeps changing the URI so run heroku redis:credentials REDIS_URL like Marcos Paolo said and get the updated REDIS_URL. – Sweetmeat

It's a good practice to set your redis URL in settings.py with OS os.environ.get('REDIS_URL')

Heroku rotates credentials periodically and updates applications where this datastore is attached.

Heroku recommends using encryption and thus a rediss:// URL instead of redis://

For celery, something like: CELERY_BROKER_URL = 'rediss://:{Password}@{Host}:{Port}'

Heroku command to get this url easy heroku redis:credentials REDIS_URL
