I get a connection error when NAKIVO Backup & Replication is trying to connect to the Transporter. How can I fix it?


When NAKIVO Backup & Replication is trying to connect to the Transporter, you may encounter an error, which can occur due to the following reasons:

  • No response was received at <hostname or IP>:<port>

    • Solution: Double-check the provided credentials and make sure that the server housing the Transporter is not down.

  • Connection to <hostname or IP>:<port> was refused

    • Solution: Make sure that the entered IP address and port are correct.

  • An internal error has occurred

    • Solution: Check your connection and try refreshing the Transporter in a few minutes.

  • Target transporter is out of date

    • Solution: Update the Transporter software to the current version.

  • Target transporter is already added

    • Solution: Check if the Transporter was already added to the product previously.

  • Incorrect master password

    • Solution: Make sure to double-check the entered master password.

  • Certificate (self-signed, CA-signed, CA cert) has expired, has changed, was removed, or is missing

    • Solution: Make sure both NAKIVO Backup & Replication and the target Transporter are updated. Also, check if the machine housing the Transporter is operational.

  • Transporter ID has changed

    • Solution: Try restarting the Transporter service. In case the problem persists, update or reinstall the Transporter.

  • Pre-shared key  has changed, was removed, or is missing
