Blocked local/private host: {host}

Error message

Blocked local/private host: {host}

What it means

validate_url blocks hosts classified as local/private (loopback, private ranges). browser_open targets the user's real browser, so an internal address would either fail uselessly or probe internal services; the check runs after https and allowlist presence checks.
