Steps to reproduce

I have set up a simple Node.JS server for companion. When uploading from local, the upload works without issue, but the Websockets always fail.

I have searched the docs and tried everything but to no avail, so it seems there is a bug here, as the code is correct.

const express = require('express');
const companion = require('@uppy/companion');
const { json, urlencoded } = require('body-parser');
const session = require('express-session');
const cors = require('cors');
require('dotenv').config();

const app = express();
app.set('trust proxy', 1);

// CORS configuration for website.com
app.use(cors({
    origin: ['https://website.com', 'https://www.website.com'],
    credentials: true
}));

// Secure session configuration
app.use(session({
    secret: process.env.SESSION_SECRET,
    resave: false,
    saveUninitialized: false,
    cookie: {
        secure: true,
        httpOnly: true,
        domain: '.website.com',
        sameSite: 'none'
    }
}));

// Basic middleware
app.use(json());
app.use(urlencoded({ extended: true }));

app.use(function(req, res, next) {
    res.setHeader('Access-Control-Allow-Origin', '*');
    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE', 'FETCH');
    res.setHeader('Access-Control-Allow-Headers', 'Content-Type');
    res.setHeader('Access-Control-Allow-Credentials', true);
    next();
});

// Companion options
const companionOptions = {
    server: {
        host: 'uppy.website.com',
        protocol: 'https',
        path: ''
    },
	companionUrl: 'https://uppy.website.com',
    secret: process.env.COMPANION_SECRET,
    debug: true,
	filePath: 'temp',
	uploadUrls: true,
	providerOptions: {
  s3: {
    key: process.env.AWS_ACCESS_KEY_ID,
        secret: process.env.AWS_SECRET_ACCESS_KEY,
        bucket: 'website-files',
		Bucket: 'website-files',
        region: process.env.AWS_REGION,
	  acl: 'private',
  },
		dropbox: {
        key: process.env.DROPBOX_KEY,
        secret: process.env.DROPBOX_SECRET,
        // redirectUri: 'https://uppy.website.com/companion/oauth/callback'
    },
		 drive: {
    key: process.env.GOOGLE_KEY,         // OAuth Client ID
    secret: process.env.GOOGLE_SECRET,   // OAuth Client Secret
	redirectUri: 'https://uppy.website.com/drive/callback',		 
    // Optionally specify the scopes you need:
    // scope: ['https://www.googleapis.com/auth/drive.readonly'],
     //redirectUri: 'https://uppy.website.com/connect/google/callback'
  },
},

    corsOrigins: [
        'https://website.com',
        'https://www.website.com',
        /^https:\/\/.*\.website\.com$/
    ],

    redisUrl: process.env.REDIS_URL,
    metrics: false,
    // sendSelfEndpoint: 'https://uppy.website.com/companion'
};

const http = require('http');
const server = http.createServer(app);

// Attach Companion's WebSocket support to the HTTP server
companion.socket(server, companionOptions);
// Initialize companion
const companionApp = companion.app(companionOptions);

// Mount companion
app.use('/', companionApp);
app.use('/api', companionApp);

// Health check endpoint
app.get('/health', (req, res) => {
    res.json({ status: 'healthy', name: process.env.AWS_S3_BUCKET });
});

// Error handling
app.use((err, req, res, next) => {
    console.error('Server error:', err);
	const errorDetails = {
  		name: err.name,
  		message: err.message,
  		stack: err.stack
	};
	res.status(500).json(errorDetails);
    // res.status(500).json({ error: 'Internal server error', err: err });
});

const port = process.env.PORT || 3000;


server.listen(port, () => {
    console.log(`Companion server running on port ${port}`);
});

The server seems right, but I've been getting those errors for upload with download link and also with GoogleDrive uploads. If you try to upload anything with the link provided, you won't be able to do it.

Expected behavior

The upload should work for Google Drive and Direct download link.

Actual behavior

When working with Google Drive or a Download link it always fails with the following error:
RequestClient.js:386 WebSocket connection to 'wss://uppy.website.com/api/22059dc6-b67e-4a10-9b75-7df5df9c6c2d' failed: (anonymous) @ RequestClient.js:386 reconnectWebsocket @ RequestClient.js:385 (anonymous) @ index.js:56 (anonymous) @ retry_operation.js:116 (anonymous) @ index.js:54 pRetry @ index.js:31 (anonymous) @ RequestClient.js:449 (anonymous) @ RateLimitedQueue.js:148 _call2 @ RateLimitedQueue.js:231 run @ RateLimitedQueue.js:113 (anonymous) @ RateLimitedQueue.js:144 (anonymous) @ RateLimitedQueue.js:143 createWebsocket @ RequestClient.js:457 (anonymous) @ RequestClient.js:520 _awaitRemoteFileUpload2 @ RequestClient.js:336 (anonymous) @ RequestClient.js:296Understand this errorAI loggers.js:30 [Uppy] [14:07:57] Companion socket error {"isTrusted":true}, closing socket

Maybe it helps to look at the standalone version to see what we do different:

Or if you don't add anything besides Companion, you can just use the standalone version.
