Connect to the Linux server that requires a second login, and keep reporting errors: the remote channel is closed

Using ssh to connect to the Linux server that requires a second login, the location of the second authentication password is always entered, and the error is reported: the remote channel is closed

使用ssh 连接需要二次登录的linux服务器，一直在输入二次验证密码的位置，同时报错：remote channel is closed


No source files or tests are named. Start by reproducing the SSH connection to a Linux server that requires a second login, then inspect where the remote channel closes during the second password prompt. Done means the second authentication completes without repeated prompting or a “remote channel is closed” error.
