I build an online shop when my customers buy something from the shop, when they reach checkout, I use hyperpay API, so when they pay by visa, its a request from my server to hyperpay server then I have the result if it the success I send an email message to customer and store payment and products data in another server with api. not always but sometimes, my server stop after sending emails, or stop before sending data to the second server, or I get a response from hyperpay and the operation cut, I don't know why. So I think it's a time-out problem, but I am still not sure. and another problem, my jquery scripts response take a long time. so I want to know, the problem with my codes or from my server?
