【求助】海外IP模拟账户回测一直报错：Read timed out. (read timeout=30)

我用的是TQSIM模拟账户来做回测。

from tqsdk import TqApi, TqBacktest, TqSim, TqAuth, ta
from tqsdk.tafunc import time_to_datetime
from datetime import date
import sys
 # 设置回测时间
start_dt = date(2025, 1, 1)
end_dt = date(2025, 5, 1)
 try:
    # 初始化模拟账户，初始资金 10 万
    acc = TqSim(init_balance=10000)
    print("初始化模拟账户，初始资金: 10000")
     # 初始化 TqApi
    api = TqApi(
        account=acc,
        backtest=TqBacktest(start_dt=start_dt, end_dt=end_dt),
        web_gui=True,
        auth=TqAuth(tq_username, tq_password)
    )
    print("TqApi 初始化成功")
     # 获取合约和 K 线数据
    symbol = "SHFE.rb2501"
    try:
        klines = api.get_kline_serial(symbol, 60 * 60)
        # 转换 K 线的时间戳为可读格式
        klines["datetime_readable"] = klines["datetime"].apply(time_to_datetime)
        print(f"K 线 datetime_readable 第一行: {klines['datetime_readable'].iloc[0]}")
        print(f"K 线 datetime_readable 最后一行: {klines['datetime_readable'].iloc[-1]}")
    except Exception as e:
        print(f"获取 K 线数据失败: {str(e)}")
        raise Exception(f"无法获取 {symbol} 的 K 线数据: {str(e)}")
     # 获取账户和持仓对象
    account = api.get_account()
    position = api.get_position(symbol)
    print(f"初始账户余额: {account.balance}, 可用资金: {account.available}")
     # 主循环
    while True:
        try:
            # 等待数据更新
            api.wait_update()
             # 等待新 K 线数据
            if not api.is_changing(klines):
                continue
            ### 策略 ###
         except Exception as e:
            # 捕获所有异常
            print(f"运行时错误: {str(e)}")
            break
 except Exception as e:
    # 捕获初始化阶段的错误
    print(f"初始化失败: {str(e)}")
    sys.exit(1)
 finally:
    # 确保 TqApi 关闭
    try:
        api.close()
        print("TqApi 已关闭")
    except Exception as e:
        print(f"关闭 TqApi 失败: {str(e)}")

但是一直显示 ReadTimeout: HTTPSConnectionPool(host=’auth.shinnytech.com’, port=443): Read timed out. (read timeout=30)

请帮忙看一下谢谢！
