错误：心跳：sidekiq中的连接丢失（ECONNRESET）

Question

I'm trying to run Sidekiq 5.2.2 on Rails 5.2 but I always get a connection lost error. Below are my server logs:

# bundle exec sidekiq -q v2_default,2 -q v2_low -e production
TID-2yed0 INFO: Booting Sidekiq 5.2.2 with redis options {:url=>"redis://myserver.lmf979.0001.apse1.cache.amazonaws.com:6379/1", :network_timeout=>7, :id=>"Sidekiq-server-PID-3644"}
TID-2yed0 INFO: Running in ruby 2.3.5p376 (2017-09-14 revision 59905) [x86_64-linux]

TID-xhh1g ERROR: Error fetching job: READONLY You can't write against a read only slave.
TID-xhh1g WARN: Redis::CommandError: READONLY You can't write against a read only slave.
TID-xhh1g WARN: /usr/local/rvm/gems/ruby-2.3.5/gems/redis-4.0.2/lib/redis/client.rb:119:in `call'

and this is my config/initializers/sidekiq.rb

Sidekiq.configure_server do |config|
    config.redis = { url: 'redis://myserver.lmf979.0001.apse1.cache.amazonaws.com:6379/1', network_timeout: 7 }
end

Sidekiq.configure_client do |config|
    config.redis = { url: 'redis://myserver.lmf979.0001.apse1.cache.amazonaws.com:6379/1', network_timeout: 7 }
end

I verify that I can do ping PONG with the server but I don't know why sidekiq can't connect.

# rails c production
Running via Spring preloader in process 7372

2.3.5 :001 > require "redis"

2.3.5 :002 > redis = Redis.new(url: 'redis://myserver.lmf979.0001.apse1.cache.amazonaws.com:6379/1')
 => #<Redis client v4.0.2 for redis://myserver.lmf979.0001.apse1.cache.amazonaws.com:6379/1> 
2.3.5 :003 > redis.ping
 => "PONG" 
2.3.5 :004 > 

Any ideas?

I was just pointing to a wrong redis endpoint in AWS. Thanks to Pavel Mikhailyuk for pointing out.
