Issue Nginx $_SERVER['HTTP_HOST'] incorrect

We discovered a weird setting where php's $_SERVER['HTTP_HOST'] is always set to the domain alias's target. Previously, expected and on a copy of the same subscription, its supposed to display the current url.
This is necessary because of Prestashop Multistore.
main url: url.nl
Alias: URL.com (not 301 redirected)
On the index (/) opening .com its displaying the .nl as HTTP_HOST.


However, creating a seperate php file to dump the exact same code, its correct:



I believe it has something to do with the proxy of nginx.

The copy we have created a month ago does not contain the *_ip_default.conf file.

I have:

fastcgi_param HTTP_HOST $host;

set in 'Additional nginx directives'.

$host does seem to be the correct value:





Any further info can be given.

Could you please confirm if any of the domains is assigned as "Default site" in Tools & Settings > IP Addresses?

Hi Sebahat,
Thanks for checking. I guess it's set correctly?


I've assigned on ipv4 only, sharing the same ip.
