Upstream sent too big header

Description:
I'm running a 502 Bad Gateway with a plugin call in this setup.
The NGINX error log says:

2020/05/04 08:58:53 [error]2020/05/04 08:58:53 [error] 2695#0: *1 upstream sent too big header while reading response header from upstream, client: 126.194.94.41, server: localhost, request: "GET /wp-admin/edit.php?s=&post_status=all&post_type=product&_wpnonce=84b4da8cb5&_wp_http_referer=%2Fwp-admin%2Fedit.php%3Fpost_type%3Dproduct%26paged%3D4&action=l$

I just need some guidance on which file should I edit.
Some guides on internet says to add 'proxy_buffer_size' others says 'fastcgi_buffers' or 'fastcgi_buffer_size' ... but I don't know where to change it.

Any tips?
