OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=error: certificate verify failed (unable to get local issuer certificate)

Question

There are a ton of posts about this. I have looked at so many of them. Zero of the fixes seem to work.

(main)> PayPal:         


        

Answer 1

As PayPal has changed TLS, so the easiest way (fastest) was to resolve as monkey patch. This patch says to use all default settings

module PayPal::SDK::Core
  module Util
    module HTTPHelper
      def configure_ssl(http)
        http.tap do |https|
          https.use_ssl = true
          https.verify_mode = OpenSSL::SSL::VERIFY_PEER
          add_certificate(https)
        end
      end
    end
  end
end
