Disable Internal Error page or hide Internal IP

Despite the right configuration in Nginx

proxy_pass_header Server;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;

As well as this in the NextCloud configuration file

‘forwarded_for_headers’ => array(‘HTTP_X_FORWARDED_FOR’),

I can’t seem to have it working properly.

I followed this thread as well, no luck so far → How to get the real IPs in logs - #37 by wwe
