EC2 instance processing fails. The following error message appears:
Internal error has occurred while backing up/replicating/recovering the instance.
Possible Cause
Closed Ports
NAKIVO Backup & Replication requires the following TCP ports to be open for successful instance processing:
TCP Port # (Default) | Where | Description |
|---|---|---|
| 4443 | Director | Used to access the Director web UI. Must be open on the Director machine. |
| 9446 | Transporter | Used by the Director and Transporters to communicate with the Transporter. Must be open on the Transporter machine. |
| 9448-10000 | Transporter | Used by Transporters for cross-Transporter data transfer. Must be open on the Transporter machine. |
Verify that:
- The ports are not used by other applications.
- The ports are not blocked.
- The ports are accessible from the appropriate endpoints.
Resources Outage
- The source or target Transporter might be disconnected or powered off.
- AWS might be temporarily unavailable in the source or target region/availability zone.
Make sure all Transporters are available and AWS is available.
