Fix Duplicacy Web Login Problems

Local dashboard access depends on the correct management address and configured administration password.

Quick answer:

Local dashboard access depends on the correct management address and configured administration password.

Steps for Windows

  1. Confirm that the Web Edition process or Windows service is running.
  2. Open http://127.0.0.1:3875 from the same computer.
  3. Check firewall or alternate listening-address settings.
  4. Use the developer's recovery instructions if an admin password was lost.

How to verify the result

The dashboard opens through the intended local URL.

Important limitation

Do not bypass authentication by exposing the interface to an open network.

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.
