Background

My dev environment is Windows, Rails cache_store worked fine for redis V2.

I am implementing ActiveJob with sidekiq, which required redis >= v3

I installed Redis for Windows from GitHub, I tried both V4 and V5.

Windows setup

Ran the installation .msi file

After install and re-boot, checked the redis-cli and connected and tested fine.

Rail setup

from config/environments/development.rb

  config.cache_store                = :redis_cache_store, { url: 'redis://localhost:6379/0' }

Rails console

>> Rails.cache => #<ActiveSupport::Cache::RedisCacheStore options={:namespace=>nil, :compress=>true, :compress_threshold=>1024, :expires_in=>nil, :race_condition_ttl=>nil} redis=#<Redis client v4.2.5 for redis://localhost:6379/0>>>> Rails.cache.redis.connected?=> false>> t = Rails.cache.fetch('test') { 'T' }=> "T">> r = Redis.new => #<Redis client v4.2.5 for redis://127.0.0.1:6379/0>>> r.get 'test'=> "123">> r.connected?=> true

Question

What am I doing wrong in my config?
