php 7.2 – Magento2 Category Page 502 Bad Gateway

I have a multi-store running Magento2.3, I am getting issues with one category page i.e
The category product listing page frontend is working fine for the USA Store view. But for the CA store view it’s showing 502 Bad Gateway in the frontend, rest of everything is working fine on the website for both store view.
Any help will be appreciated.
