I am building a laravel application that will use commerce coinbase to accept payments. I have implemented all the necessary things. I have added the webhook route to the exceptions in VerifyCsrfToken.
On Coinbase send test page, if I pass any website design with laravel example laracast, I will get the "Failed to establish a connection" error message. However, if I pass other website, it will establish connection. Below is the picture of the error.
