App deployed on gets disconnected from server just for some users once in a while

I've successfully deployed two applications on You can find them here:

The problem is that for some users, once in a while, the application doesn't start, but the frustrating part is that I got no logs error message! There's just the grey screen with the popup that says "Disconnected from server".
What happens is exactly the same that this user experienced with his Shiny app:!searchin/shinyapps-users/disconnected|sort:date/shinyapps-users/MizC2f8Eaj8/i8G0pbDwBgAJ

In addition, the strangest thing is that this error never happens on my machine, and after I try to check what's happening, I successfully connect to my app and then also the users that were experiencing the error can connect.

I have no clue on how to solve this also because I can't reproduce the error. Any suggestion and idea would be super appreciated! Thanks a lot!
