I have been using heroku redis for a while now on one of my side projects. I currently use it for 3 things
- It serves as a place for me to store firebase certificates
- It is used for caching data on the site
- It is used for rails sidekiq jobs
Recently, my heroku usage went up and I had to change it to use heroku redis premium plan. Ever since then I have been getting error: SSL_connect returned=1 errno=0 state=error: certificate verify failed (self signed certificate in certificate chain)
somehow. Everything stayed the same yet the error started popping out of nowhere.
Does heroku-redis premium plan work fundamentally different than a basic heroku-redis plan?
I am using ruby on rails, deployed on heroku with heroku redis if that helps.
Actually, when you install the Heroku Redis on your heroku app, it will create for you 2 Config Vars : REDIS_TLS_URL and REDIS_URL.
The docs are actually incorrect, you have to set SSL to verify_none because TLS happens automatically.
