Heroku Redis cant open connection

Question

I following Ryan Bates tutorial ActionController Live, and deploying app at heroku. All works fine, except events, where Ryan sad that we should reopen the redis connection, and I cant do it. I using RedisToGo to perform redis on heroku. Here my events controller action:

def events
    response.headers["Content-Type"] = "text/event-stream"
    redis = Redis.new(:url => uri)
    redis.psubscribe('messages.*') do |on|
        on.pmessage do |pattern, event, data|
            response.stream.write("event: #{event}\n")
            response.stream.write("data: #{data}\n\n")
        end
    end
    rescue IOError
        logger.info "Stream closed"
    ensure
        redis.quit
        response.stream.close
end

Also here redis initializer:

uri = URI.parse(ENV["REDISTOGO_URL"])
REDIS = Redis.new(:url => uri)

Can someone help me?

EDIT

I got all to work just initializing the client using Redis.new(url: ENV["REDISTOGO_URL"]) instead of parsing the URI in events controller action.

replace this:

redis = Redis.new(:url => uri)
redis.psubscribe

with this:

REDIS.psubscribe

anywhere you have 'redis' above, replace with the REDIS global.

you have that REDIS = Redis.new in your config/initializers somewhere, right? – court3nay May 15 '16 at 19:09
Also have this line in create controller action: REDIS.publish('messages.create', @message.to_json) – jealrockone May 15 '16 at 19:14
at=error code=H12 desc="Request timeout" dyno=web.1 connect=0ms service=30000ms status=503 bytes=0 Find this error in server logs, its causes if i dont open the connection in events action – jealrockone May 15 '16 at 19:17
