Problem Description
When using vscode to connect to a remote linux server ssh login suddenly fails to connect, showing Resolver error: Error

Personal solution:

1. Use other remote connection software to log in to the server, the blogger used Tabby
2. Use the command to find your own related processes: ps -ef | grep user_name
3. Find the pid of the process corresponding to .vscode, end the corresponding process: kill -9 $pid
4. vscode reconnect

Note:
For the time being, we do not know the reason for this frequent problem, but the above method can solve the connection failure problem.
