Ionic 4 platforms/browser/www when moved to the server and reload ger error "cannot get page"

Hello, I have one question. How can help me ? ionic 4 platforms / browser / www when I moved it to the server, and I’m doing a reload. I see that “cannot get page”. But navigation worked.

Remove this two folders platforms and www

And build the project… They are created when your build…

:wink:
