I am using WooCommerce plugin in WordPress on my shopping site. All of a sudden I am getting Error 502 Bad Gateway as soon as I add a product in cart.
This is not happening for all products though. I tried latest product which I added a couple of days ago and it is fine. Then I tried 4, 5 other random products and they are showing this error.
I even changed from “Proxied” to “DNS Only” in CloudFlare control panel but same issue.
Site is hosted on a VPS and nothing has been changed.
