Cannot make 2.0.9 work as Windows Service

Support

Hi all,
I had Duplicati 2.0.8 installed and working. I wanted to try Canary 2.0.9 and tried the following:

  • uninstalled 2.0.8 but kept database in C:\ProgramData\Duplicati\Data
  • installed 2.0.9
  • executed Duplicati.WindowsService.exe install --server-datafolder=C:\ProgramData\Duplicati\Data --webservice-password=password which executed successfully
    The I tried to connect to http://localhost:8200 but I’m getting a ERR_CONNECTION_REFUSED error
    I also tried Duplicati.GUI.TrayIcon.exe --no-hosted-server --webservice-password=password but I’m getting the following error:
C:\Program Files\Duplicati 2>Unexpected error: System.AggregateException: One or more errors occurred. (Es konnte keine Verbindung hergestellt werden, da der Zielcomputer die Verbindung verweigerte. (localhost:8200))

Welcome to the forum @starob

Were there Windows operations to stop, start, or restart the service anywhere in that sequence?

It sounds like the service was either not started or went down. You can watch it in Task Manager.

Thanks for your support. Indeed the service was not running. I started it but it I still cannot login. I always get “Not logged in” even after entering the correct password at http://localhost:8200

Try a new tab, or if you want to test on current tab, try refresh. If that fails, try hard refresh.

I think I had to hard refresh once, but I haven’t figured out a reproducible way to need that.

I have noticed that the service is not started after being installed.
Would it be more logical if it started the server after install?

If you use 2.0.9.106 I have added logging to Windows Event Viewer, so you should be able to view some additional error messages there. But as @ts678 suggested, it might be the login page that is cached with the 2.0.8 version and a browser hard refresh (CTRL+F5) should fix the login page.

I’m answering as starob2 because my starob account is on hold?

Yes, absolutely. If I install a windows service it should start immediatly. At least that is my opinion. Actually it would be even better to make the Windows Service installation an option in the installation program.

CTRL+F5 did the job, thank you.

But I have a few other questions/issues:

  1. Is 2.0.9.106 fully compatible with 2.0.8.1 in regard to backing up/restoring data? I restored files from a 2.0.8.1 backup and got a hash mismatch error for one exe file. At some point there was also a message about encryption but it disappeared and never showed up again.
  2. I started Duplicati.GUI.TrayIcon.exe --no-hosted-server --webservice-password=password but it behaves strange, almost unusable. Windows asked if it should kill the process and I did. Tried this a few times but always the same.
  3. When there is a backup job scheduled for a time slot that happens to trigger while my notebook is in standby I’m getting a “Cannot connect to server” error. I assume that is related to Windows Modern Standby somehow. I tried many things like disabling WiFi during standby but I could not prevent that from happening. This is also the case with version 2.0.8.1

Appreciated your support. Thanks

Update: I fixed #2 by checking “Prevent tray icon automatic log-in”. Strangely enough it does not ask me for a password but auto logs in. Probably because I added --webservice-password=password.

I approved that account; it was caught in some anti-spam guard.

Yes, the remote data format has not changed, so you can freely go back-n-forth, at least as far as the files go.

Not sure why that option should change the “almost unusable” state. The option just disables pre-fetching a signin token for the url to open when clicking “Open”. When not opening the page from the trayicon, the option should have no effect on the TrayIcon or Server/Service.

The reason why you are not asked for a password, is likely because you are already logged in via the browser. If you click the “Logout” menu and close the tab, opening from the trayicon should once again ask you for a password.

It sounds like the network is disabled during standby but Duplicati is not suspended.

I have added an issue for pausing/delaying backups while in Modern Standby state.
