I also add addon Redis to go

Answer 1

Your application should not try to connect to the localhost. Instead, your initializer should fetch the env var ( REDIS_URL IIRC) and use it if it exists.

Answer 2

Make sure you have Redis installed. I know you said you got this on Heroku, but for example, if you were on a Mac and were using Homebrew, you could simply run brew install redis , and you'd be good to go. (It fixed it for me, anyway.)
