My Redis is running in background but apparently Sidekiq is not connecting to it. Any ideas?

  • Redis is running
  • gem 'redis-rails' is installed
  • gem 'sidekiq', '~> 5.0', '>= 5.0.5' is installed
  • Ruby -v: ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]
  • Rails -v: Rails 5.1.6

After I run: ps aux | grep redis

 redis    21875  0.2  0.0  42044  6208 ?        Ssl  17:47   0:00 /usr/local/bin/redis-server 127.0.0.1:6379

Console after running bundle exec sidekiq:.
