Nodejs (express) server is hosted on Ubuntu 16.04. Using nginx as reverse proxy many sub-domains are pointing to same sever. I have integrated payment gateway which after successful transaction redirects to a URL. However after sometime nginx returns response of 504 Gateway Time-out. At the same time if I try to access same api from postman I get success response.
As this redirect is caused by payment gateway service, in request header it shows
Origin: https://secure.ccavenue.com Referer: https://secure.ccavenue.com
I am not sure how to bypass this through nginx.
