I have a problem with Heroku and my ReactJS application on the front-end side. I have RESTfull API with Ruby on Rails uploaded on the Heroku server ( to do some testings before I purchase actual hosting), and suddenly from today, i cannot use my API on the Heroku, due Privacy and SSL errors ( I didn't change or update anything on Heroku and the API). I got those errors on the browser :
I cannot find any solution online. Any suggestion?
