In my case I was able to just 'ssh user@host' first and it offered to auto-generate the key for me which was then saved for subsequent sessions.

I solved same problem with this command:

rsync --rsh="/usr/bin/sshpass -p "password" ssh -o StrictHostKeyChecking=no -l root" /source/file/path username@192.168.1.1:/destination/file/path

Note: Be sure about each side has sshpass installation before usage.

Host Key Verification Failed

This post does good job explaining the issue. In short:

The host key for domain.com has changed. If this does not seem fishy to you, you can remove the old key from your local cache using

ssh-keygen -R domain.com

Try to connect first simply using ssh only, then post adding it to known hosts try sshpass, etc. as required.

In my case, I had done a clean new install of linux distro and installed sshpass and it started giving errors, they all went away as soon as I connected first via ssh and added the remote server's IP in the known hosts.

I have just hit this same issue now when trying to rsync data between 2 servers:

$ sshpass -p<my_password> rsync -avzh $VOLUME_PATH/*.chk user@server:${TARGET_PATH}
Host key verification failed.
rsync error: unexplained error (code 255) at rsync.c(638) [sender=3.1.1]

The error was misleading though - to fix the issue I had to install rsync on the target server as well. I am not sure why this is required but once both the source and target servers had rsync installed the copy went through.

I had same problem, the reason was I was using IP address which was set in Cloud Flare CDN, and CF masks IPs. I used domain name instead and problem resolved.
