Increase file upload size doesn't work (nginx.conf / php.ini)

I’d like my site visitors to be able to upload photos through a simple form. I’m using Statamic CMS (v2) that’s been deployed via Laravel Forge.

I’ve added client_max_body_size 20M; in the http section of my nginx.conf file (/etc/nginx/nginx.conf);

I’ve also modified upload_max_filesize and post_max_sizein two php.ini files (/etc/php/7.4/fpm/php.ini and /etc/php/7.4/cli/php.ini), both to allow 20mb file uploads.

After those modifications I restarted my nginx web server (systemctl restart nginx).

The good thing: when I try to upload a file larger than 2 mb and submit the form, I no longer get a ‘431 entity too large’ error, but the form just seems to doesn’t work. Like it submits the entry into the void.

Am I overlooking something?

Thanks!
