brew install mkcert
brew install nss
mkcert -install
mkcert mywebsite.test "*.mywebsite.test"

Add the code below to your config/puma.rb

if ENV["RAILS_ENV"] == "development"
  clear_binds! # Remove the tcp:// binds that stops ssl:// to work
  ssl_bind "0.0.0.0", 3000, {
    key: File.join("config", "local-certs", "mywebsite-key.pem"),
    cert: File.join("config", "local-certs", "mywebsite.pem"),
    verify_mode: "none"
  }
end

So, to start your server you can do

rails s

instead of

rails s puma -b 'ssl://0.0.0.0:3001?cert=config/local-certs/mywebsite.pem&key=config/local-certs/mywebsite-key.pem&verify_mode=none&no_tlsv1=false&no_tlsv1_1=false'
