Hi Hui LIU 刘辉,
Thank you for posting. Please understand that Chinese is not currently supported on the Q&A forum.
Are you using SSH keys for authentication? Make sure that the key files exist and are correctly configured. Try regenerating the key pair and update the server's public key.
If there is firewall or security software running on your computer, disable it temporarily to see if the SSH connections are blocked. You can also try some different SSH client like PuTTY.
If the issue persists, open the Event Viewer and check the "Application" or "System" logs for any errors or warnings related to SSH connections.
Best Regards,
Ian Xue
