Adjust the client_max_body_size directive value as needed.

To apply the upload size limit to all sites, create a file named increase_upload_size_limit.conf (the name can be anything) in the ~/frappe/services/nginx-proxy/confd directory with the following content:

client_max_body_size 100m;

For a specific site, such as example.com, create a file named example.com_location in the ~/frappe/services/nginx-proxy/vhostd directory with the following content:

client_max_body_size 100m;

After making the above changes, restart global-nginx-proxy using the following command

fm services restart global-nginx-proxy

Edit the file located at ~/frappe/sites/<bench name>/configs/nginx/conf.d/default.conf and modify the client_max_body_size directive:

client_max_body_size 100m;

After making the above changes, restart bench's nginx-proxy using the following command

fm start <bench name> -f

This can be done via the dashboard or by editing site_config.json.

1. Open Frappe Desk.
2. Navigate to Search > System Settings.
3. In the Files tab, change the Max File Size (MB) field.

1. Open site_config.json in your preferred editor.
2. Add the key "max_file_size": "104857600" (100 MB), with the value in bytes.
