Does the Nginx configuration not allow file uploads?

Hello,
The Nginx configuration is:

# CORS Origin Mapping (keep your existing map)
map $http_origin $cors_origin {
    default "";
    "~^http://(localhost:3000|localhost:3001)(:[0-9]+)?$" $http_origin;
    "~^http://172\.20\.2\.58(:[0-9]+)?$" $http_origin;
}
server {
    listen 80;
    server_name 172.20.2.58 localhost;
    # Security headers (keep existing)
    add_header X-Frame-Options "SAMEORIGIN" always;
    add_header X-Content-Type-Options "nosniff" always;
    root /home/docki/real/portal/public;
    index index.php index.html;
    
     # Increase max upload size (adjust as needed)
    client_max_body_size 100M;

When I try to upload a file to the site, the following error is displayed:

Upload

The Nginx report is as follows:

2025/06/02 03:51:55 [warn] 24869#24869: *203 a client request body is buffered to a temporary file /var/lib/nginx/body/0000000005, client: 172.21.50.67, server: 172.20.2.58, request: "POST /api/waxGuards/1 HTTP/1.1", host: "172.20.2.58", referrer: "http://172.20.2.58/waxGuards"

Is there a problem with the Nginx configuration or is this an error on the back-end side?

Thank you.

Not totally sure, but the error is actually a warning that NGINX is buffering. It shows that NGINX successfully received the body request and buffered it. However, I can’t tell (and it doesn’t show) what happened after it passed it on.

I do not see anything wrong in the NGINX configuration. I suggest you might want to look at the Laravel logs and also make sure php.ini also has the approprate limits.

So likely a back-end problem.

To add to what @davemc said, you are getting an Axios error. Axios is a JS API library so the core issue lies in whatever JS your backend runs. There might be some other NGINX error too, but the first step is to fix the JS backend.
