Windows Server service

Good afternoon. I am testing with duplicacy on a server with Windows Server 2012. I have installed it correctly and it works perfectly when making copies, but, when I close the session, it stops making the copy that I was making and also I can no longer access the web remotely from another computer.
I have reinstalled the web application and indicated that I want it to run as a service, and apparently, in the application monitor it appears that the service is running, but when I log out it does not continue to work correctly.

Can you help me?

Thank you very much to all.

Can you access the web page while the service is running?

There might be some error message in the log file C:\ProgramData\.duplicacy-web\logs\duplicacy_web.log.
