Can't connect to redis on heroku

Set REDIS_PROVIDER to the name of the env var with your Redis URL.

Type this: heroku config:set REDIS_PROVIDER=REDISTOGO_URL. Restart.

Explained here: https://github.com/mperham/sidekiq/wiki/Using-Redis#using-an-env-variable

Setting REDIS_URL in heroku config help me to resolve:

Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED) (Redis::CannotConnectError)

You must set the REDISTOGO_URL on Heroku.

Click on Settings, and then Reveal Config Vars.
