Duplicati2 has been working well for months on a Windows11 23H2 notebook (all updates for 23H2 are installed). I recently updated Duplicati to 2.1.0.4 and now things don’t quite work any more.
When I click the Duplicati icon on the Desktop, I get a red-blinking icon in the dock and when I click on it a message telling me that the PC does not have a suitable app to open that link. When I open http://localhost:8200 in a browser, I get a Duplicati window asking me for a password, which I don’t have.
The “lost password” link on that page takes me to a Duplicati documentation page suggesting to look for the password with EventManager, but there I have not been able to find anything. I only found messages from the Restart Manager that it could not restart C:\Program Files\Duplicati 2\Duplicati.GUI.TrayIcon.exe because the Program-SID did not agree with the Conductor-SID as well as a message about
Duplicati.WebserverCore.Exceptions.UnauthorizedException: Authorization failed due to missing cookie.
at Duplicati.WebserverCore.Endpoints.V1.Auth.<>c.<b__3_0>d.MoveNext()
I would much appreciate any suggestions for how to get Duplicati to work again. I mostly work with macOS and have very little experience with Windows, so I would greatly appreciate suggestions useful to Windows novices.
What could be happening is that you are already running Duplicati somehow, and the TrayIcon is detecting this and trying to activate the other instance.
I have not heard this reported as an error before though.
This indicates that Duplicati is indeed running. Are you running Duplicati as a service? As a different user?
I think the first message is the launch problem, where one instance is already running as a different user than you try to start it with.
The second one is an attempt to log in without a valid password.
First, you need to figure out where Duplicati is running. I suggest stopping this, possibly using TaskMgr.exe if you cannot get a handle on the instance.
If you do not need to run as a Service, it should be a simple matter of starting Duplicati, and then it will show the start page where you can change the password. If not, right click the TrayIcon and choose “Open” and you can change the password in settings.
If you need to run as a service, let me know and I will try to guide there.
