unix client: key check failed

[flip]

We have to sftp from an unix client to a Coreftp server.
When connecting we are getting the error:
Received disconnect from xxx.xxx.xxx.xxx: 2: key check failed
Connection closed

The strange thing is that, when I remove the public key on the client side, it's asking for a password and then we don't get the error.
We have this issue on both Aix and on Solaris clients.

On the CoreFTP server, the "Allow key authentication" is enabled.

Any help would be appreciated.

Exact same issue - please advise if you found a solution.

Client has new public fingerprint. Suspect the client key needs to be updated but where is the public key file location?

Thanks
