Error: Cannot Reach SFTP Server
Validate host, port, firewall, and container port mapping before retrying SFTP backup destination.
Meaning
Runtime could not establish TCP session to configured SFTP endpoint.
Triage Steps
- Re-check host and port values in provider form.
- If Docker is involved, use published host port, not container internal port.
- Confirm firewall/security group allows inbound SSH/SFTP.
- Test reachability using terminal tools from same network context.
Connectivity Check
telnet your-host 22
# or
nc -vz your-host 22
