Error: Tianqin Api will lose websocket connection every night after 19:30

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

[x] I have reviewed the documentation.
[x] I have tried to use the latest version tqsdk==3.7.1.
[x] I have searched the issues for an answer to my question and I think other issues are caused by this problem like https://github.com/shinnytech/tqsdk-python/issues/483

Environment(for bug reports)

[x] Operating System: Ubuntu 24.04.1 LTS (GNU/Linux 6.8.0-40-generic x86_64)

My configuration/Related code

import time
from datetime import datetime
from tqsdk import TqApi, TqAuth

tq_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())
