title: Herkou Redis - certificate verify failed (self signed certificate in certificate chain)
body: <p>I have been using heroku redis for a while now on one of my side projects. I currently use it for 3 things</p>
  <ol>
  <li>It serves as a place for me to store firebase certificates</li>
  <li>It is used for caching data on the site</li>
  <li>It is used for rails sidekiq jobs</li>
  </ol>
  <p>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 <code>error: SSL_connect returned=1 errno=0 state=error: certificate verify failed (self signed certificate in certificate chain)</code> somehow. Everything stayed the same yet the error started popping out of nowhere.</p>
  <p>Does heroku-redis premium plan work fundamentally different than a basic heroku-redis plan?</p>
  <p>I am using ruby on rails, deployed on heroku with heroku redis if that helps.</p>
