我原先是把VNPY架设在阿里云
以前是可以正常登入的，但今年来就登入CTP错误，显示登入交易服务器错误，代码：75，但是我换成本地端的机器，同一个帐号登入CTP就能成功
请问这是什么情形？代码：75是什么意思，谢谢您了

VN Studio 跟 tws 连线，只要 tws 掉线重启后 Vn Studio 就会停止接收行情数据。
之前的 tws 是每日必需要注销离开，现在增加了自动重启的功能

但是tws自动重启后 Vn studio还是没能继续接收行情数据
请问站长VNPY能不能考虑增加断线重新连上的功能呢 ?

看过站长之前发的帖子，也试着操作过，但还是没能成功，所以想跟站长求助，该如何解决
谢谢您了
