Browsing to a non-existing webpage should display a 5xx error page

Expected Behavior

Browsing to a non-existing address should display a 5xx error page.

Current Behavior

It shows a blank page (loads nothing)

Possible Solution

Update the DAppContainer component to listen for webview did-fail-load events. In such a case, render a custom component that gives details about the errorCode and errorDescription.

Sorry. To clarify, I meant the game in the 404 page. I don’t think a 404 page should be “future”.

Aren’t there two different cases, requestion unexisting host (cannot be resolved) and requesting a non-existent resource from a host. I believe in the first case nos client should show placeholder (nos domain cannot be resolved) but in the second case, it is the responsibility of a dApp to handle requests to non-existent pages (error 404) and errors (5xx).
