SFTP Authenticate with Public/Private Key Pair

[Garate77]

Hi,

We are trying to connect to the SFTP using Public/Private Key Pair, but keep getting the following error:

    "Connection failed

    Authentication failed for user user_test@xyz.domain.com"

Workato IPs have been whitelisted and with the same keys we are able to connect with Filezilla for example. Any assistance will be welcome.

We have a situation where a client has given us a .key file.  Whenever i try to import in Filezilla says its a public key. Please correct me if wrong. We need both private key and public key for connection to their SFTP or we generate private and public key and share the public key to them?
