Nginx Sites Not Showing on 4G LTE But Work On Wifi and LAN

Just did some more probing to know more on this by comparing working hamaracity.com to non working holyshrines.in by giving same parameters for test. Yes, both sites are on Certboot SSL. But Hamaracity hosts just HTMLs but holyshrines is running Wordpress. Please go through once and suggest

Did you mean to check this instead? (Try with four A's, not three.)
