MediaPlayer HTTP stream from the same EndPoint does work

[Aroxed]

I follow the example "examples/server/server.py" and try to use audio streaming capability of the MediaPlayer. It works when I use third-party URL (https://radio.liferadiolive.com:1580/stream) but never starts a URL from the same web application as the example. My IP Address is 192.168.0.100, the code is here:

async def offer(request):
   ...
    player = MediaPlayer('https://192.168.0.100:8000/stream') # blocks execution forever
    # player = MediaPlayer("https://radio.liferadiolive.com:1580/stream") # works perfectly
    # player = MediaPlayer(os.path.join(ROOT, "demo-instruct.wav")) # works perfectly

I try to feed the media player with stream data from the same host and I implemented the function:

async def handle_stream(request):
    response = web.StreamResponse()
    response.headers['Content-Type'] = 'audio/pcm'  # Modify content type as per your audio format
    await response.prepare(request)

    while True:
        try:
            # Read data from the queue and write it to the response stream
            data = await queue.get()
            await response.write(data)
        except asyncio.CancelledError:
            break

    return response

and added the URL here:

queue = asyncio.Queue()
app = web.Application()
app.on_shutdown.append(on_shutdown)
app.router.add_get("/", index)
app.router.add_get("/client.js", javascript)
app.router.add_post("/offer", offer)
app.router.add_get("/stream", handle_stream)
web.run_app(
    app, access_log=None, host=args.host, port=args.port, ssl_context=ssl_context
)

My problem is that "handle_stream" never calls. Is this disabled by design or am I doing something wrong?

Thanks in advance.
