IPN was not sent, and the handshake was not verified. Review your information.

Hello PayPal

I had many tried to add IPN url in paypal IPN simulator.

But get this error "IPN was not sent, and the handshake was not verified. Review your information."

As well as I had already configured SSL algorithm in my website.

Can you please provide the solution for this quick issue.

Regards,
