Solutions

1. Confirm the URL loads directly in Chrome without an interstitial warning (e.g. certificate error or safe-browsing page).
2. Fix the site's SSL certificate if Chrome shows a certificate interstitial.
3. Make sure the server responds correctly to requests for the tested URL.

When it happens

Trigger: Raised when Chrome shows an interstitial (e.g. certificate warning or safe-browsing page) instead of loading the target URL.

Common situations: See trigger scenarios.
