Is there an existing issue for this?

  • [x] I have searched the existing issues

OS/Web Information

  • Web Browser: Firefox 143.0.4
  • Local OS: Fedora 41
  • Remote OS: Ubuntu 24.10
  • Remote Architecture: amd64
  • code-server --version: 4.105.1 811ec6c1d60add2eb92446161ca812828fdbaa7f with Code 1.105.1

Fresh install, my first try using it. I tried reinstalling twice (while removing the cached file), including once from dpkg and .deb package instead of just .sh install script like on the previous tries. Blank page and such errors in the firefox console

Steps to Reproduce

Well this one is awkward, because I am using it in my personal quart service on an endpoint with such proxy code (I want to give access to me and few of my friends on my home server):

# --- Code-server logic ---
code_server_sessions = {}

async def start_code_server(username):
	if username in code_server_sessions:
		return code_server_sessions[username]['port']

	if not os.path.exists(f"/home/ubuntu/code_servers/{username}"):
		os.makedirs(f"/home/ubuntu/code_servers/{username}/ext", exist_ok=True)

	port = random.randint(5200, 5300)
	while port in [session['port'] for session in code_server_sessions.values()]:
		port = random.randint(5200, 5300)
	command = [
		"code-server",
		"--bind-addr", f"127.0.0.1:{port}",
		"--auth", "none",	
		"--user-data-dir", f"/home/ubuntu/code_servers/{username}",
		"--extensions-dir", f"/home/ubuntu/code_servers/{username}/ext",
		"--disable-workspace-trust",
		"--disable-telemetry",
		"--disable-update-check"
	]
	env = os.environ.copy()
	env["CODE_SERVER_DISABLE_CSP"] = "true"
	proc = subprocess.Popen(command, env=env)
	code_server_sessions[username] = {
		'process': proc,
		'port': port
	}
	await asyncio.sleep(2)
	return port

@app.route("/vscode/", defaults={'path': ''}, methods=['GET', 'POST', 'PUT', 'DELETE', 'PATCH'])
@app.route("/vscode/<path:path>", methods=['GET', 'POST', 'PUT', 'DELETE', 'PATCH'])
@login_required
async def proxy_vscode(path):
	username = current_user.username
	port = await start_code_server(username)
	qs = request.query_string.decode()
	target = f"http://127.0.0.1:{port}/{path}" + (f"?{qs}" if qs else "")
	
	async with httpx.AsyncClient(follow_redirects=True, timeout=httpx.Timeout(60.0, read=60.0)) as client:
		req = client.build_request(
			request.method, target,
			headers = {k:v for k,v in request.headers.items() if k.lower() not in ("host", "cookie")},
			content = await request.get_data()
		)
		resp = await client.send(req, stream = True)

		async def stream_response():
			try:
				async for chunk in resp.aiter_bytes():
					yield chunk
			except httpx.ReadError as e:
				print("ReadError while streaming:", e)
				return

		headers = [(k, v) for k, v in resp.headers.items() if k.lower() != 'content-security-policy']

		headers.append((
			"Content-Security-Policy", "default-src * 'unsafe-inline' 'unsafe-eval' data: blob:;"))

		return Response(
			stream_response(),
			status = resp.status_code,
			headers = headers
		)
	
@app.websocket("/vscode/<path:path>")
@login_required
async def vscode_proxy_ws(path):
	username = current_user.username
	port = await start_code_server(username)
	qs = websocket.scope["query_string"].decode()
	target = f"ws://127.0.0.1:{port}/{path}" + (f"?{qs}" if qs else "")

	try:
		async with websockets.connect(target, subprotocols = websocket.headers.get_list('Sec-WebSocket-Protocol')) as backend_ws:
			async def front_to_back():
				try:
					while True:
						msg = await websocket.receive()
						await backend_ws.send(msg)
				except websockets.exceptions.ConnectionClosed:
					pass
				
			async def back_to_front():
				try:
					async for msg in backend_ws:
						await websocket.send(msg)
				except websockets.exceptions.ConnectionClosed:
					pass
			
			await asyncio.gather(front_to_back(), back_to_front())
	except Exception as e:
		app.logger.error(f"VSCode WebSocket proxy error for user {username}: {e}", exc_info=True)

Expected

Well, I expected it to load. I debugged some of quart-side proxy code errors and I think it should be fine there, so I resorted to asking here if this might be a code-server issue. But I still might be wrong.

Actual

Site empty, return codes 200 on everything, errors in console:

Are you accessing code-server over a secure context?

If you try to open workbench.js and nls.messages.js directly in your browser, what do they look like? It looks like maybe they are returning something other than JavaScript, or they are corrupt in some way.

Are you able to access it directly without the proxy just to test?
