ssh [email protected] @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that a host key has just been changed. The fingerprint for the ECDSA key sent by the remote host is SHA256:PQUODpEoQ0NmEP1KwgwI39FGCXXXXX2h+gsw1g+peU. Please contact your system administrator. Add correct host key in C:\Users\hanleng/.ssh/known_hosts to get rid of this message. Offending ECDSA key in C:\Users\hanleng/.ssh/known_hosts:4 ECDSA host key for 192.168.xxx.xxx has changed and you have requested strict checking. Host key verification failed.

The reason for this issue is usually that the SSH key of the remote server may have been regenerated or changed. For example, the server might have been reinstalled or reconfigured, resulting in a new SSH key being generated.

  1. Open File Explorer and navigate to the C:\Users\hanleng\.ssh\ directory.
  2. Locate the known_hosts file and open it with a text editor.
  3. Find the line related to 192.168.xxx.xxx and delete it.
  4. Save the file and close the editor.
  5. Reconnect, and you will be prompted to accept the new host key. Type yes and continue with the connection.
