I open an app that has been sleeping for nearly one year. Rediscloud cancelled the DB in the meanwhile.I have a new Rediscloud DB, with REDISCLOUD_URL on a redis://default:(key)@redis-(path) format.But Sidekiq cannot connect on Rediscloud.
My Redislabs.com linked with my app asserts 'This subscriptiondoes not contain any databases'
Do I have to launch/initialize rediscloud DB in some way ? Does the default: generate a missing authorization ACL ? Or is the problem due to my redis gem version 4 ?
Here is my Gemfile abstrac. It used to work perfectly one year ago, before I put the app on sleep. That's why I haven't changed versions yet, and I'm still on heroku-18 :
ruby '2.6.5'gem 'rails', '~> 6.0.2', '>= 6.0.2.1'gem 'redis', '~> 4.0'gem 'sidekiq'gem 'sidekiq-failures', '~> 1.0'Here are my logs :
