Sometimes I got this pop-up window it says: 'Login failed - Server disconnected, please try again'. And if I didn't click the button 'OK' to confirm, it seems the TWS will not try to connect again and then the connection lost.
After I anaylisis the log in attached file, I found that it happened in server rset time (such as Second reset: 20:15 - 21:00 HKT ). As my TWS server is in HongKong, so it seems it was coursed by server reset.
Anyway, for this problem, if IBC can add new auto click button behavior to confirm to reconnect to server when login failed?
After all, the connection maybe lost by other reasons and we need keep TWS online again ASAP.
Thank you very much.

BTW, you can found server reset time here: https://www.interactivebrokers.com/cn/index.php?f=2225
