get_quote_history 获取多个标的时不稳定

在日常使用中，使用get_quote_history获取多个标的时，（最近）出现多次获取失败，无响应的的情况，请问大佬有什么改善的方法？

Start by reading and reproducing get_quote_history with multiple securities, using the behavior described in the issue and its attached screenshot as the baseline. Trace the request path and determine whether repeated multi-security calls fail or hang. Done means the multi-security history retrieval responds reliably, with an appropriate regression check for the reported failure.
