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: root@iZj6cgi365ov99veqodfgnZ-app:/var/www/discourse# cat /etc/nginx/nginx.conf user www-data;

} } 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.

[image] tumbleweed: 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 It seems like you’re trying to solve two problems at once? Disabling image compression is done by changing Admin - Settings - Files - recompress original jpg quality to 100. The other issue is about upload file size. [image] tumbleweed: still receive a “file too large” error when uploading images larger than 15MB Can you please post the exact error? [image] tumbleweed: with composer media optimization image disabled Does it work with this setting enabled?

you have to change the nginx config client_max_body_size value inside discourse docker as well
