Hello guys,
It seems you removed HMWP lines from nginx config. If it’s the case please get them again from HMWP and add them to Nginx config file.
If they are already there, this means you placed them in a wrong place. In this case let me know your server provider, OS and location of nginx config file (you attached above) please also attach following files:
common/wpfc-php7.conf;
common/wpcommon-php7.conf;
common/locations-php7.conf;
