Hi, I am new to Intuit developer community and trying to use OAuth2 with Laravel 5.4 but getting the error page when I click on Connect to QB button.

We're sorry! We're experiencing some problem. Please try again later. Any help will be much appreciated.

I found the solution for this specific issue: Just had to add the Redirect URI.
