交易连接失败返回-1

import random

from xtquant.xttype import StockAccount
from xtquant.xttrader import XtQuantTrader

# miniQMT安装路径
mini_qmt_path = 'D:\\国金证券QMT交易端\\userdata_mini'
# QMT账号
# 创建session_id
session_id = int(random.randint(100000, 999999))
print(session_id)
# 创建交易对象
xt_trader = XtQuantTrader(mini_qmt_path, session_id)
# 启动交易对象
xt_trader.start()
# 连接客户端
connect_result = xt_trader.connect()
print("connect_result",connect_result)

本地python版本是3.12

结果一直返回-1，没有连接成功，是什么原因？
