我已经在MERN堆栈中创建了一个基于电子商务的应用程序，后端托管在AWS EC2中，前端托管在Vercel中。所以我的问题是在AWS EC2中托管后端后，我看到我无法打开支付网关。我猜测可能是AWS本身阻止了支付URL访问。在我的Chrome浏览器的网络选项卡中，它显示504 gateway timeout错误，strict-origin-when-cross-origin。但在AWS托管之前，我也尝试了OnRender平台在那里托管，它工作得很好。
我在获取超时错误时所做的事情-在AWS中，我将安全组中的出站规则设置为http和https，并且还有入站规则ssh，https和http。但我仍然无法访问支付网关。我使用Eazebuzz支付getway。
我正在共享路由和控制器
我的路由是本地透视http：//localhost：5000/API/schemes/：id/initiate_payment
