Could not find a solution similar to my setup. I've installed redis on DigitalOcean from this guide. All seems ok and can see all systems are running. I'm using rails so I installed the sidekiq gem. Everything works on local computer.
config/initializers/sidekiq.rb looks like:

I see few tabs and the one that's causes the issue is the "Scheduled" tab. After adding a job to the job queue, I get the an error as in title, in production. Not sure where to raise the issue: Sidekiq or redis itself. Has anyone seen this issue before? I'm not a redis expert, sorry.
