为什么订阅周、日、小时K线都正常，而订阅月K线时就会提示超时及网络错误？
klinesM = api.get_kline_serial(SYMBOL,30*24*60*60,data_length=i) # 30日

return f(self, *args, **kwargs)

raise TqTimeoutError(“获取 %s (%d) 的K线超时，请检查客户端及网络是否正常” % (symbol, duration_seconds))
tqsdk.exceptions.TqTimeoutError: 获取 [‘INE.ec2504’] (2592000) 的K线超时，请检查客户端及网络是否正常
