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

Hi ,

Wishing everyone, A Happy New Year.

Our Dynamic websites having SSL or otherwise (wordpress & Drupal) running on Nginx are failing on LTE/4G connections on mobiles. Strange as it may appear, non-dynamic sites, even on SSL are appearing fine on 4g/LTE connections. This may have something to do with ipv6 or ipv4.

There is no issue with 4G data provider as other HTML sites are running fine. As usual, at each browser test, cache has been autoclaved till the last bite.

Thanks in advance,

Dr. OSK Raju

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.)
