When internet connection lost, MVC page(view) returns “the page can not be displayed”

My page gets data from db and when internet connection lost, the page return “the page can not be displayed”. The point is, page is used on a monitor without control panel. So, page must get datas automatic.

The script that i used for refreshing page:

<meta http-equiv="refresh" content="@ViewBag.AndonRefreshSec" />

But it can’t provide that i want. How can i solve the problem?
