Training Content
Common Chrome-Specific Failure Patterns

Symptom Likely Blocked Domain(s) Notes
Users see blank content or modules that never load
cdn.cyberescape.livingsecurity.com
*.cloudinary.com
*.contentful.com
ctfassets.net
 Chrome Safe Browsing or corporate proxy filters often block CDN/asset domains. Check if Enhanced Protection is enabled in chrome://settings/security
Login succeeds but content fails to launch
identity.livingsecurity.com
platform-cdn.livingsecurity.com
 SSO or token handoff blocked. Chrome may block third-party cookies - check chrome://settings/cookies. Ensure "Allow all cookies" or add livingsecurity.com to allowed sites
Progress not tracking or completion not recorded
events.launchdarkly.com
app.launchdarkly.com
api.events.unlayer.com
 Chrome extensions (uBlock Origin, Privacy Badger, AdBlock) often block analytics/feature flag domains. Test in Incognito mode to bypass extensions
Training partially loads with missing images or CSS
*.contentful.com
*.cloudinary.com
 Chrome's Site Isolation or extensions may block these as cross-origin requests. Check if "Block third-party cookies" is enabled
Video content fails to play or buffers indefinitely
*.cloudflarestream.com
videodelivery.net
cdn.cyberescape.livingsecurity.com
 Corporate proxies with SSL inspection interfere with video streaming. Chrome's hardware acceleration may also cause issues - disable at chrome://settings/system
Works in Incognito but fails in regular Chrome
Any of the above +
*.livingsecurity.com deeper subdomains
 Extension conflict detected. Disable extensions one by one at chrome://extensions. Common culprits: ad blockers, privacy tools, VPN extensions, script blockers
Works on personal device but fails on corporate Chrome
Any of the above +
*.livingsecurity.com
All CDN domains
 Chrome Enterprise Policies enforced by IT. Check chrome://policy for blocked domains. Company may enforce Enhanced Protection, cookie blocking, or extension policies
Console shows CORS or mixed content errors
identity.livingsecurity.com
platform-cdn.livingsecurity.com
*.contentful.com
 Chrome's strict CORS enforcement blocks cross-origin requests. Corporate proxy may be modifying headers. Check if "Insecure content" is blocked at chrome://settings/content/insecureContent
Intermittent loading issues or random failures
All platform domains
 Chrome's aggressive preloading/caching may serve stale content. Clear cache (Ctrl+Shift+Delete) and ensure "Preload pages" is set appropriately at chrome://settings/performance
Pop-ups or new tabs blocked during authentication
identity.livingsecurity.com
*.livingsecurity.com
 Chrome's pop-up blocker prevents SSO flows. Check chrome://settings/content/popups and add livingsecurity.com to allowed sites. Corporate policies may override this
Quick Chrome Diagnostic Steps:
1. Test in Incognito mode (Ctrl+Shift+N) to rule out extensions
2. Check chrome://settings/cookies - allow all or whitelist livingsecurity.com
3. Check chrome://settings/content/popups - allow livingsecurity.com
4. Check chrome://policy for enterprise restrictions
5. Disable extensions at chrome://extensions
6. Clear cache/cookies (Ctrl+Shift+Delete)

Subject: Request: Verify Access for Living Security Training Platform on Google Chorme

Hi [Customer IT Team],

We’re seeing that users on Google Chrome are unable to fully load or complete training modules in Living Security’s platform, though everything functions correctly in MS Edge. This behavior typically indicates that one or more platform domains are being blocked or modified by Edge’s Tracking Prevention settings or by corporate proxy filters.

To ensure smooth access, please verify that all traffic to the following domains is allowed over port 443 and is not subject to filtering, inspection, or content rewriting:

 
app.livingsecurity.com
identity.livingsecurity.com
livingsecurity.com
*.livingsecurity.com
*.*.livingsecurity.com
*.contentful.com (specifically cdn.contentful.com)
*.cloudinary.com (specifically living-security-res.cloudinary.com)
*ctfassets.net (specifically assets.ctfassets.net and images.ctfassets.net)
platform-cdn.livingsecurity.com
cdn.cyberescape.livingsecurity.com
events.launchdarkly.com
app.launchdarkly.com
api.unlayer.com
api.events.unlayer.com

 

Once these domains are fully whitelisted, Chrome users should be able to access all Living Security training content normally.

General Blank Page 

1. Open the dashboard in an Incognito Window (no extensions)

Extensions are the #1 cause of blank SPA pages.

How to test:

  1. Click ⋮ (top right).

  2. Select New Incognito Window.

  3. Go to page again, example: https://dashboard.livingsecurity.com.

If it loads here, an extension is blocking scripts.

If it works:

Disable extensions one-by-one:

  1. Go to chrome://extensions

  2. Toggle off:

    • uBlock / AdBlock

    • Ghostery

    • Privacy Badger

    • NoScript

    • Any “security”, “privacy”, or “script blocking” tools

  3. Refresh the dashboard.

2. Try without the corporate network / VPN

Corporate web filtering tools (Zscaler, Netskope, Cisco Umbrella, etc.) often block script bundles or API calls without showing an error.

Quick test:

  • Turn off VPN (if on).

  • Connect to a mobile hotspot or home Wi-Fi.

  • Try the dashboard again.

If it loads off the corporate network:

Their IT team must allowlist dashboard and API domains. You can tell me the network errors and I’ll help identify which domains are blocked.

3. Clear site data just for Living Security

Chrome may have cached a broken JS bundle.

How to do it:

  1. Go to the URL bar.

  2. Click the lock icon → Site settings.

  3. Scroll down → Clear data.

  4. Reload the dashboard.

4. Turn off Chrome tracking/cookie restrictions

Strict cookie or tracking settings can block authentication scripts.

Steps:

  1. Go to chrome://settings/cookies

  2. Set to Allow all cookies (at least temporarily).

  3. Under Customized behaviors, ensure:

    • livingsecurity.com is Allowed

    • *.livingsecurity.com is Allowed

Then refresh the dashboard.

5. Check for popup or redirect blocking (SSO issue)

If Chrome blocked a redirect during login, the page can get stuck blank.

Steps:

  1. Go to chrome://settings/content/popups

  2. Add URLs, example:

    • https://livingsecurity.com

    • https://dashboard.livingsecurity.com
      to the Allow list.

Then retry logging in.

6. Do a hard refresh (forces Chrome to reload scripts)

Sometimes Chrome caches a half-loaded file.

Windows shortcut:
Ctrl + Shift + R (or) Ctrl + F5

7. Check Chrome DevTools for blocked requests

You’ll see errors if Chrome is blocking scripts or corporate filters are interfering.

How to check:

  1. Press F12.

  2. Click Console → look for red errors.

  3. Click Network, then reload the page → look for:

    • blocked by client (extension)

    • ERR_SSL

    • ERR_CONNECTION_RESET

    • 403 / 401

    • CORS errors

Send me a screenshot of the Console or Network tab and I can pinpoint the exact cause.
