Issue accessing website from behind proxy, while the same website hosted in different hosting works fine even behind proxy

my website veganmall.in is having issues when accessing from behind VPN/proxy. while the cloned replica of this site tveganmall.000webhostapp.com does not have any issue. veganmall.in is hosted in hostinger and tveganmall.000webhostapp.com is hosted in in.000webhost.com. Trying to troubleshoot issue i see that the http & https headers are getting different values for both these sites. Any help or pointer here to fix the issue with veganmall.in is highly appreciated as the hosting provider hostinger could not troubleshoot the issue and have pointed me to this forum to take help from. Thanks in advance.

I also noticed that veganmall.in has Head: tag and https://in.000webhost.com/ has :authority tag in the http request headers if that makes any significance.

Please find below the curl -I output with and without proxy for https and http headers for both sites for comparison
