Sidekiq processing with local redis but not with remote

Question

I have a RoR app with background jobs using whenever and sidekiq gems.

In development environment when I launch sidekiq with local redis instance (on localhost) the job keeps getting executed without problems. But when I switch to a remote redis instance (Heroku add-on) and restart sidekiq, it says it started processing, but nothing happens and workers aren't doing any jobs.

Here's my config/schedule.rb (for whenever gem)

every 2.minutes do
  rake "crawler:crawl"
end

Here's my initializers/redis.rb:

Sidekiq.configure_server do |config|
  config.redis = { :url => 'redis://user:[email protected]:9098/' }
end

Sidekiq.configure_client do |config|
  config.redis = { :url => 'redis://user:[email protected]:9098/' }
end

If I comment out the content in redis.rb and run a local redis instance, the jobs are processed normally. But when I use this remote redis instance, this shows up and then nothing gets processed:

Maybe you connecting to wrong redis database or not connected at all. In my apps I use redis url without trailing slash. In your case:

This is for database "0"

redis://user:[email protected]:9098

And this for database "1"

redis://user:[email protected]:9098/1
