Browser Troubleshooting - MS Edge
Common Edge-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 |
Edge tracking prevention or proxy filters often block CDN/asset domains. Check if Enhanced Security Mode is set to "Strict" at edge://settings/privacy |
| Login succeeds but content fails to launch |
identity.livingsecurity.com
platform-cdn.livingsecurity.com |
SSO or token handoff blocked. Edge may block third-party cookies - check edge://settings/content/cookies. Ensure "Block third-party cookies" is OFF or add livingsecurity.com to exceptions |
| Progress not tracking or completion not recorded |
events.launchdarkly.com
app.launchdarkly.com api.events.unlayer.com |
Edge's Tracking Prevention (Strict mode) blocks analytics/feature flag domains. These domains handle progress tracking. Test in InPrivate mode to bypass extensions |
| Training partially loads with missing images or CSS |
*.contentful.com
*.cloudinary.com |
Edge may block these as cross-site or third-party sources. Enhanced Security Mode (Strict) is particularly aggressive. Change to "Balanced" mode or add exceptions |
| 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. Edge's hardware acceleration may also cause issues - disable at edge://settings/system. Check if WebRTC is blocked |
| Works in InPrivate but fails in regular Edge |
Any of the above +
*.livingsecurity.com deeper subdomains |
Extension conflict or corrupted cache detected. Disable extensions at edge://extensions. Common culprits: ad blockers, privacy tools, VPN extensions. Clear browsing data completely |
| Works in Chrome, fails in Edge corporate build |
Any of the above +
*.livingsecurity.com deeper subdomains |
Indicates Edge privacy/proxy enforcement unique to enterprise policies. Check edge://policy for Group Policy restrictions. Corporate build may enforce Enhanced Security (Strict), tracking prevention, or SmartScreen blocks |
| Console shows CORS or mixed content errors |
identity.livingsecurity.com
platform-cdn.livingsecurity.com *.contentful.com |
Edge's strict CORS enforcement or Enhanced Security Mode blocks cross-origin requests. Corporate proxy may be modifying headers. Check if site is blocked by SmartScreen at edge://settings/privacy |
| Intermittent loading issues or random failures |
All platform domains
|
Edge's aggressive startup boost/sleeping tabs may interfere with platform. Disable "Startup boost" and "Sleeping tabs" at edge://settings/system. Clear cache (Ctrl+Shift+Delete) and restart Edge completely |
| Pop-ups or new tabs blocked during authentication |
identity.livingsecurity.com
*.livingsecurity.com |
Edge's pop-up blocker or SmartScreen prevents SSO flows. Check edge://settings/content/popups and add livingsecurity.com to allowed sites. Enhanced Security Mode may also block legitimate pop-ups |
| Platform works briefly then stops responding |
All platform domains
WebSocket connections |
Edge's Sleeping Tabs feature suspends inactive tabs. Disable at edge://settings/system under "Save resources with sleeping tabs". May also indicate WebSocket connection issues with corporate firewalls |
| SmartScreen warnings or "not secure" messages |
*.livingsecurity.com
All subdomains |
Microsoft Defender SmartScreen may flag new domains or misclassify legitimate sites. Request IT to whitelist at edge://settings/privacy or report false positive to Microsoft. Corporate policies may prevent users from bypassing warnings |

Subject: Request: Verify Access for Living Security Training Platform on Microsoft Edge
Hi [Customer IT Team],
We’re seeing that users on Microsoft Edge are unable to fully load or complete training modules in Living Security’s platform, though everything functions correctly in Chrome. 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, Edge users should be able to access all Living Security training content normally.
