The Duplicacy Web Edition default listening address is localhost:3875.
Steps for Windows
- Verify that Duplicacy Web Edition is installed and running.
- Open the default local address in a browser.
- If it fails, inspect installed-service status and port conflicts.
- Review Settings before changing the listening address.
How to verify the result
The local dashboard is reachable without public port forwarding.
The port is part of local management, not the backup data destination itself.
Why this matters
The practical goal is a recoverable Duplicacy revision, not just a successful-looking progress indicator. Keep your source, backup destination, Backup ID and necessary credentials documented. If this workflow changes your retention or storage configuration, verify a restore before applying it to important data.
