哪位高手能帮忙看下这个python websocket连接该怎么写？

import asyncio
import websockets
import json


async def subscribe_without_login_index(url, channels):
    while True:
            async with websockets.connect(url) as ws:
                sub_param = {"method": "SUBSCRIBE","params":channels,"id": 1}
                sub_str = json.dumps(sub_param)
                await ws.send(sub_param)
                while True:
                    try:
                            res_b = await asyncio.wait_for(ws.recv(), timeout=55)
                    except (asyncio.TimeoutError, websockets.exceptions.ConnectionClosed) as e:
                            try:
                                await ws.send('pong')
                                res_b = await ws.recv()
                                print(res_b)
                            except Exception as e:
                                print("连接关闭，正在重连……")
                                break
                            await asyncio.sleep(1)
                    if 'event' in res_b:
                        continue


url = 'wss://fstream.binance.com/ws/<!markPrice@arr>'
channels = ["!miniTicker@arr"]
loop = asyncio.get_event_loop()
loop.run_until_complete(subscribe_without_login_index(url, channels))
loop.close()

运行后报错： TimeoutError: [Errno 10060] Connect call failed ('104.244.46.185', 443)。

其中wss接口url: wss://fstream.binance.com/ws/<!markPrice@arr>

订阅一个信息流: 

• 请求

  {
  "method": "SUBSCRIBE",
  "params":["!markPrice@arr],
  "id": 1
  }

我用websocket 网站测试是OK的，如下图所示：

但是用python弄不出来，有高手能指点下吗？
