I assume service status was from Task Manager `Services` tab or `Services` tool linked on there.  
That tool could attempt to add some logging to file after Duplicati.WindowsService.exe launches Duplicati.Server.exe. [Duplicati.WindowsService.exe](https://duplicati.readthedocs.io/en/latest/07-other-command-line-utilities/#duplicatiwindowsserviceexe) shows how to do that at initial service install, however the Windows `Services` tool lets you amend a startup line (`Path to executable`) later.

I don’t know if you also run Duplicati.TrayIcon.exe. If so, a full set of processes is shown under

What happens? Is there an error message (like you get with service down), or does it sit silently?

If it can’t, logs at Duplicati level for web server startup and browser activity are pretty minimal, but _maybe_ can help.

The [netstat](https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/netstat) command can show if anything is working at the usual Duplicati port (probably 8200). Because you run a service, you probably need an Admin prompt in order to look at Duplicati use:
