Vaadin Offline Not working

Hi guys, I installed my Vaadin Flow application in a remote area where internet connection is a problem. The error I get i localhost refused to connect.

Please describe exactly what and how you wanna do it. There are no problems with running Vaadin application on production in closed on premise solutions. Keep in mind that you can’t access the application via localhost if you deploy them somewhere else. Looks of the started application would probably help to see if you build or started it wrongly.
