What should you do if you encounter the error 'No credentials found for types SSH password or SSH private key'?

When encountering the error 'No credentials found for types SSH password or SSH private key', the most appropriate action is to create and validate an SSH credential. This error indicates that the ServiceNow instance does not have the necessary authentication information to connect to the target devices via SSH.

Creating an SSH credential involves adding the relevant username and password or private key to the ServiceNow Credential Store, which the Discovery process will use to establish a secure connection. Validating the SSH credential ensures that it is correctly set up and can authenticate successfully against the intended devices.

This approach directly addresses the issue at hand by providing the required credentials for SSH communication, thus enabling successful data discovery. Without proper credentials, the Discovery process will fail to retrieve information from devices, making credential management a key aspect of ensuring automated discovery operations run smoothly.

The other options do not target the core issue:

• Rebooting the MID Server may resolve some connectivity issues but does not address the lack of credentials.

• Updating the SSH protocol to a newer version is unlikely to fix credential-related problems, as the error specifically states that credentials are missing.

• Changing network configuration settings might help with connectivity but cannot resolve issues stemming from a lack of valid authentication credentials.
