python-3.x - 在heroku上托管python websockets

Question

我正在尝试在 heroku 上托管我的 websocket 应用程序。我目前正在我的 app.py 文件中启动我的服务器，如下所示：

def startme():
    start_server = websockets.serve(main_connect,'',os.environ.get('PORT'))
    asyncio.get_event_loop().run_until_complete(start_server)
    asyncio.get_event_loop().run_forever()

我的 Procfile 看起来像这样：

web: gunicorn app:startme

查看日志，它启动正常，显示它正在运行的端口，如下所示：

[2021-04-30 23:37:06 +0000] [4] [INFO] Listening at: http://0.0.0.0:35403 (4)

但是当我尝试连接它时，就像这样：

uri = "wss://myapp.herokuapp.com/0.0.0.0:35403"
async with websockets.connect(uri) as websocket: #connects

我只是在服务器上收到此错误：
