ruby on rails 4 - Heroku not locating redis server -

still having trouble connecting redis on heroku. works fine locally.

i installed 'redis' gem , located redistogo_url within heroku website. added production env variable heroku.

when try run carrierwave backgrounder process depends on redis , sidekiq, keep getting error below.

redis.rb

uri = uri.parse(env["redistogo_url"]) redis = redis.new(host: uri.host, port: uri.port, password: uri.password) 

in config file

if rails.env.development?   env['redistogo_url'] = 'redis:://@localhost:6379' else   env["redistogo_url"] = 'redis://redistogo:my_hash_key@greeneye.redistogo.com:9286/' end
