The ArchiveMind page does not open

Symptoms

ArchiveMind seems to start (or you are sure you launched it), but no window appears — or the browser shows "can't connect" / "site can't be reached" at http://127.0.0.1:8765/.

What this usually means

Either the app window failed to open while the app itself is running, or the local server is not actually running (it was never started, it stopped, or its port is taken).

Safe steps to try

  1. Give it ~15 seconds after launching — on a slow disk, startup can take a moment — then go to http://127.0.0.1:8765/ in any browser yourself.
  2. Check the address carefully: http://127.0.0.1:8765/ — plain http, not https.
  3. Check whether ArchiveMind is running in Activity Monitor (macOS) or Task Manager (Windows).
  4. Try another browser if you have one — this separates a browser problem from an app problem.
  5. Quit and reopen safely: see Restarting ArchiveMind safely.

What not to delete or change

  • Do not delete the catalogue database or the application-data folder.
  • Do not change firewall, proxy, or network settings for this — the page is served machine-internally and does not cross the network.
