SSH: “REMOTE HOST IDENTIFICATION HAS CHANGED”

Hello,

I’m am trying to connect to my slice VM through bastion.fabric-testbed.net from Windows 11 with OpenSSH. SSH is repeatedly reporting “REMOTE HOST IDENTIFICATION HAS CHANGED” for the bastion, and I was wondering whether this behaviour is expected.

I can provide the host fingerprints and the (approximate) timestamp if needed.

I didn’t find anything in the knowledge base.

Do you know if the changing host fingerprints are expected? What is the suggested way to handle this?

Many thanks!
