How to connect to IBM Cloud Redis from Ruby on Rails application

Migrating from one service to IBM Cloud for Redis.

I cannot find the correct configuration to connect using TLS. Everything I find on this is related to Heroku. and it ignores verifying the TLS/SSL connection.

I cannot find how to configure our Sidekiq/Redis to connect.

I do have a certificate from the IBM Cloud dashboard and I suspect I have to pass that along somehow.

Configure the Sidekiq.yml like this

:redis:    :url: "rediss://:< PWD >@< DB Name >:< PORT >/0"    :namespace: "app"    :ssl_params:      ca_file: 'path/to/cert'

I keep getting back the error Redis::CommandError - WRONGPASS invalid username-password pair or user is disabled.: however using these same credentials in the migration script I am able to connect to the DB, so the credentials are ok, I think it is not including the certificate correctly and I cannot find the correct way to do this
