ShinyApps.io saying 'server disconnected' despite Basic Plan of Shiny

Hi guys, i got a situation, i need your help. I'm currently on a Basic plan of Shiny. Despite that my shiny app is taking at least 7 minutes to load and at the end says server disconnected which is very disappointing. A day ago it was working after 7 minutes loading time but today its not working.

Regards
