I run a website where photography enthusiasts frequently share their works, and I want to disable all image compression while enabling metadata stripping. I have made the following adjustments:
I set max image size to 40MB, set max image megapixels to the maximum allowed value of 150 MP, and disabled composer media optimization image.
I also adjusted the Nginx settings in the container.
Simply put, I added
client_header_timeout 1m;
client_body_timeout 1m;
proxy_connect_timeout 30s;
proxy_read_timeout 1m;
proxy_send_timeout 1m;
and modified
# maximum file upload size (keep up to date when changing the corresponding site setting)
client_max_body_size 200m ;
In server{} in /etc/nginx/nginx.conf.
Added
client_max_body_size 200m;
client_header_timeout 1m;
client_body_timeout 1m;
proxy_connect_timeout 60s;
proxy_read_timeout 1m;
proxy_send_timeout 1m;
in http{} in /etc/nginx/nginx.conf
Here are the configurations for /etc/nginx/nginx.conf and /etc/nginx/conf.d/discourse.conf:

Despite these changes, I still receive a “file too large” error when uploading images larger than 15MB, and with composer media optimization image disabled, the images fail to upload.
Could someone guide me on what other settings I should adjust or if there is an issue with my Nginx configuration?
I am new to Nginx and have relied entirely on Google and ChatGPT for these modifications.
