Adding client_max_body_size to nginx config returns directive duplicate error

[jhdcruz]

Adding client_max_body_size through UI nginx config, throws an error:

config invalid, rolled back to previous contents

2026/07/21 15:02:49 [emerg] 34#34: "client_max_body_size" directive is duplicate in /etc/nginx/http.d/zz-lerd-user.conf:6
nginx: [emerg] "client_max_body_size" directive is duplicate in /etc/nginx/http.d/zz-lerd-user.conf:6
nginx: configuration file /etc/nginx/nginx.conf test failed

Even after adding it manually in zz-lerd-user.conf, fails to re/start the service using systemctl --user restart lerd-nginx. lerd nginx reset and applying it again still returns that error.
Adding a custom.d does not throw an error, but does not apply it either (yes it matches the url), not sure if I just configured it wrong though.

Using lerd nginx edit throws the same error above. Not sure if this is just a misconfiguration (most likely) on my part so I'm using discussion instead of reporting as an issue.

Config:

# Lerd global nginx http-level overrides.
#
# Loaded inside the http { } block, after lerd's defaults, so your values win.
# Lerd never overwrites this file; saving reloads nginx.

client_max_body_size 100m;
# gzip on;
# gzip_types text/plain application/json application/javascript text/css;
# proxy_buffers 8 16k;
# proxy_buffer_size 32k;

Thanks,
