I got errors shown as below:

the main root cause is that I setup my Redis like this

not sure how/where to configure like that while using the gem.

So, my work around is to make sure REDIS_URL included everything.

Describe the solution you'd like

support customize Redis connection (if not implemented yet)

Describe alternatives you've considered

clear document to show how to customize connection (if it's implemented)

Additional context
nope

Usual practice is that the REDIS_URL includes the protocol so that you end up with config.redis = { url: ENV['REDIS_URL'] }

[mhenrixon]

In #571 I go through how to simply configure Sidekiq but to be honest, that question belongs more in the Sidekiq issues. Perhaps you can find some guidance on their wiki? https://github.com/mperham/sidekiq/wiki/Using-Redis

I'll go ahead and close this issue for now. Doesn't really relate to this gem as we are just using the configuration for Sidekiq to work our magic.
