Getting a “The file for this url was not found” error on tus/server

I have a @tus/server backend with a react uppy frontend. And when uploading I’m getting this response

“The file for this url was not found”

Im runnin multiple containers and the vps is behind nginx.

In the frontend I’m using uppy like this

const [uppy] = useState(() => new Uppy().use(Tus, { endpoint: 'https://app.chatzu.ai/files/' }));

the frontend does these requests in order

Request URL:
https://app.chatzu.ai/files
Request Method:
POST
Status Code:
301 Moved Permanently
Remote Address:
<IP>
Referrer Policy:
strict-origin-when-cross-origin


Request URL:
https://app.chatzu.ai/files/
Request Method:
GET
Status Code:
404 Not Found
Remote Address:
<IP>
Referrer Policy:
strict-origin-when-cross-origin

Nginx conf

    location /files/ {
        proxy_pass http://172.17.0.4:1080;
     # Disable request and response buffering
        proxy_request_buffering  off;
        proxy_buffering          off;
        proxy_http_version       1.1;

        # Add X-Forwarded-* headers
        proxy_set_header X-Forwarded-Host $host:$server_port;
        proxy_set_header X-Forwarded-Proto $scheme;

        proxy_set_header         Upgrade $http_upgrade;
        proxy_set_header         Connection "upgrade";
        client_max_body_size     0;

}

and my tus server code

const { Server } = require('@tus/server');
const { FileStore } = require('@tus/file-store');
const express = require('express');

const host = '0.0.0.0';
const port = 1080;
const app = express();
const uploadApp = express();

const server = new Server({
  path: '/files',
  datastore: new FileStore({ directory: '/files' }),
});

// Middleware to log all incoming requests
uploadApp.use((req, res, next) => {
  console.log(`[${new Date().toISOString()}] ${req.method} ${req.originalUrl}`);
  next(); // Pass control to the next middleware or route handler
});

uploadApp.all('*', server.handle.bind(server));
app.use('/files', uploadApp);

app.listen(port, host, () => {
  console.log(`Server listening on http://${host}:${port}`);
});

Thanks
