Resolution

The customer's administrator for their other application re-generated the keypair.

Broadcom loaded the new public key to the user.

The error "Auth failed. Passw Not Sent Yet. Meth that could otherwise continue: publickey,password,keyboard-interactive" indicates that the Private key on the customer's side does not match the Public key associated to the SFTP user on the Broadcom side.
