Diagnostics
Component.Studio includes a diagnostic page to help troubleshoot connectivity and compatibility issues. If you're experiencing problems loading images, slow performance, or other technical issues, the diagnostics page can help identify the cause.
What Gets Tested
The diagnostics page runs several tests and collects information about your system:
Network & Location Information
The page detects your IP address, ISP (Internet Service Provider), organization, and geographic location. This information helps identify if connectivity issues are related to your ISP or region. It's especially useful for diagnosing ISP security features that may be blocking our servers.
Browser & System Information
Details about your browser, operating system, screen resolution, available memory, CPU cores, and connection type are collected. This helps determine if your system meets the requirements for running Component.Studio effectively.
Connectivity Tests
| Test | What It Checks |
|---|---|
| SSL/TLS Connection | Verifies your browser can securely load images from our storage servers. A failure here usually indicates an ISP security feature, firewall, or antivirus blocking the connection. |
| CORS | Tests Cross-Origin Resource Sharing to ensure your browser can fetch resources from our storage. Failures may indicate browser extensions or network proxies interfering. |
| Network Latency | Measures response time to our servers. High latency (>500ms) may cause slow image loading. |
| WebSocket Support | Confirms your browser supports WebSockets, required for real-time data synchronization. |
Graphics & Performance Tests
| Test | What It Checks |
|---|---|
| WebGL Support | Required for the design canvas. Shows your GPU renderer information. |
| Canvas 2D | Required for image rendering and export functionality. |
| Available Memory | Checks if sufficient memory is available for smooth operation. |
ISP Security Features
Many Internet Service Providers include security features that can mistakenly block legitimate websites. Our image storage server uses a cloud-hosted subdomain that some ISP security filters flag as suspicious. If your SSL or CORS tests fail, the diagnostics page will detect your ISP and show specific instructions for resolving the issue.
Spectrum Security Shield
Spectrum's Security Shield is enabled by default and may block our image storage URLs.
- Quick fix: Log into spectrum.net or the My Spectrum app, go to Services & Equipment → Security Shield, and toggle it OFF.
- Alternative: Submit an unblock request at Spectrum's URL Verification page (takes 5-7 business days).
Note: Changing DNS settings (1.1.1.1, 8.8.8.8) will NOT bypass Security Shield.
Xfinity xFi Advanced Security
Xfinity's Advanced Security feature may block our servers.
- Quick fix: Open the Xfinity app, tap Account icon → xFi Advanced Security → Disable.
- Alternative: Request a re-assessment at spa.xfinity.com (takes about 3 business days).
Note: Xfinity does not offer a whitelist feature—you must disable or request re-assessment.
AT&T ActiveArmor
AT&T's ActiveArmor Internet Security may flag our storage URLs.
- Quick fix: Open the AT&T Smart Home Manager app, go to Profiles → Advanced Content Controls → Web filters, and add an exception or disable ActiveArmor.
Note: The "Allow" button in threat notifications may not work reliably.
Verizon Home Network Protection
Verizon's Home Network Protection (powered by McAfee) may block our URLs.
- To disable: Open the My Fios app → Internet → Home Network Protection → Toggle OFF.
Note: Verizon does not offer a whitelist option—disabling is the only workaround.
Sharing Diagnostic Results
After running the tests, click the Copy Results button to copy a complete diagnostic report to your clipboard. This report includes all test results, system information, and network details in both human-readable and JSON formats. When contacting support, paste this report to help us quickly understand your situation.
Common Issues & Solutions
| Symptom | Likely Cause | Solution |
|---|---|---|
| Images won't load | ISP security feature | Disable ISP security shield (see above) |
| Images load on mobile but not desktop | ISP or router blocking | Check ISP security settings or router firewall |
| Intermittent image failures | Antivirus SSL scanning | Disable SSL/HTTPS scanning in antivirus settings |
| Very slow image loading | High latency or throttling | Check latency test results; contact ISP if >500ms |
| Canvas not rendering | WebGL disabled or unsupported | Update graphics drivers; enable hardware acceleration |
