An RSA signature verification operation (block type 01) failed, typically because the public used to check the signature does not match the private key used to sign the data. Is this a server-side log or a client-side log? If the client is using the wrong private key or wrong certificate, then I'd expect to see this type of error on the server. -- Viktor.
