- [url=data:text/html,chromewebdata#buttons]Checking the proxy and the firewall[/url]
The "data:text/html,chromewebdata" URL value (called kUnreachableWebDataURL in Chromium) is loaded whenever a URL fails to load in a frame (for example, via RenderFrameImpl::didFailProvisionalLoad and LoadNavigationErrorPage). The issue you explained is kind of a bug where Android WebView built on chromium fails to loads the page in question due unmapped ssl error.
