Brief description of bug

The TQ Api will lose WSS connection every night after 19:30.

Unfortunately, it will raise an error in ops time and cause the asyncio loop to collapse. And there is no other parameter I can use to get the connection status of the WSS connection.
To solve the problem currently, I have to restart the program every night.

Self-Diagnosis

• I have reviewed the documentation.
• I have tried to use the latest version tqsdk==3.7.1.
• I have searched the issues for an answer to my question and I think other issues are caused by this problem like夜盘开始后，无法接收数据 #483

Environment(for bug reports)

• Operating System: Ubuntu 24.04.1 LTS (GNU/Linux 6.8.0-40-generic x86_64)
• IDE version: Pycharm 2024.1.5 (Professional Edition)

My configuration/Related code

import timefrom datetime import datetimefrom tqsdk import TqApi, TqAuthtq_user = ''tq_pwd = ''tq_api = TqApi(auth=TqAuth(tq_user, tq_pwd))tq_lst = tq_api.get_quote_list(['SHFE.au2504'])print(tq_lst)while True:    tq_api.wait_update(deadline=time.time() + 2.0)    dt = datetime.strptime(tq_lst[0]['datetime'], '%Y-%m-%d %H:%M:%S.%f')    print(dt.timestamp())

Steps to Reproduce the Issue
