[Msah30012001]

I have used composer require anandsiddharth/laravel-paytm-wallet package for Paytm payment gateway.

the problem i face is when I click on the payment now button. it does not redirect me to the merchant transactions page. it returns me the payment is failed.

I have updated app.php file in config. session.php and updated other required files.
