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  • Target transporter is out of date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

  • Incorrect master password.
