asyncio.exceptions.TimeoutError如何

问题遇到的现象和发生背景
我是通过asyncio异步爬取m3u8文件，总共684条，运行过程到680条左右就不动了，过一会就报asyncio.exceptions.TimeoutError超时错误
 问题相关代码，请勿粘贴截图

import requests
import re
import asyncio
import aiohttp
import aiofiles
import time
from bs4 import BeautifulSoup
import os

def get_first_m3u8_url(url):
    resp = requests.get(url)
    page = BeautifulSoup(resp.text, 'html.parser')
    div = page.find('div', attrs={'class': "stui-player__video clearfix"})
    div = str(div)
    obj = re.compile(r'url=(?P.*?)" ', re.S)
    first_m3u8_url = obj.search(div).group("url")
    return first_m3u8_url


def get_second_m3u8_url(url):
    resp = requests.get(url)
    m3u8_domain = url.replace('index.m3u8', '')
    second_m3u8_url = resp.text.split('AUdT3fzc/')[1].strip()
    second_m3u8_url = m3u8_domain + second_m3u8_url
    return second_m3u8_url


def download_m3u8_file(url):
    resp = requests.get(url)
    with open('斗破苍穹.m3u8', mode='wb') as f:
        f.write(resp.content)
    print('下载完毕')

async def download_ts(url,session,n,sem):
    n = str(n)
    n = n.zfill(4)
    async with sem:
        async with session.get(url) as resp:
            async with aiofiles.open(f"斗破苍穹动漫/{n}" + '.ts', mode='wb') as f:
                await f.write(await resp.content.read())
        print(f"{url}下载完毕")
async def dowmload_ts_file():
    tasks = []
    n = 1
    # timeout = aiohttp.ClientTimeout(total=1000)
    sem = asyncio.Semaphore(5)
    # connector = aiohttp.TCPConnector(limit=10)
    async with aiohttp.ClientSession() as session:
        async with aiofiles.open('斗破苍穹.m3u8', mode='r') as f:
            async for line in f:
                line = line.strip()
                if line.startswith('#'):
                    continue
                task = asyncio.create_task(download_ts(line, session, n, sem))
                tasks.append(task)
                n += 1
            await asyncio.wait(tasks)


def main(url):
    first_m3u8_url =get_first_m3u8_url(url)
    second_m3u8_url = get_second_m3u8_url(first_m3u8_url)
    download_m3u8_file(second_m3u8_url)
    # loop = asyncio.new_event_loop()
    # asyncio.set_event_loop(loop)
    # loop.run_until_complete(dowmload_ts_file())
    asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
    asyncio.run(dowmload_ts_file())

if __name__ == '__main__':
    url = 'https://www.9y9y.com/vodplay/19137-1-1.html'
    main(url)

运行结果及报错内容

asyncio.exceptions.TimeoutError

我的解答思路和尝试过的方法
尝试过Semaphore控制并发数，还有TCPConnector限制连接数，还有超时时间设置都不行
我想要达到的结果
成功运行
