连接堡垒机出错 Error connecting to Fortress

你好，目前我在使用2.6版本时出现了一个问题。我需要先连接堡垒机，然后选择一个角色，再输入要连接的机器密码。截图展示的是2.5版本，可以正常工作，但是在2.6版本上，当我连接堡垒机时直接提示断开连接，无法进行后续操作。
Hi, I'm currently having a problem with version 2.6. I need to connect to the bastion machine, then select a character, then enter the password of the machine I want to connect to. The screenshot shows version 2.5, which works fine, but on version 2.6, when I connect to the bastion machine I am prompted to disconnect directly and cannot follow through.

Reproduce the bastion-machine connection flow in WindTerm 2.6, using the reported sequence: connect to the bastion, select a role, and enter the target machine password. Compare the same flow with version 2.5, which reportedly works, and inspect the connection behavior around the immediate disconnect. Done means the 2.6 flow reaches the target machine password step without disconnecting.
