Troubleshooting
Login Issues
Cannot reach server
Symptoms: “Network error: Cannot reach server” or “Connection timeout: Server is not responding” message on login.
Solutions:
- Verify the Host URL is correct
- Check your internet connection (WiFi or mobile data)
- Try opening the Host URL in a web browser to confirm the server is reachable
- If using a corporate network, check if a VPN is required
- If the server is not responding, try again later or contact your administrator
Invalid credentials
Symptoms: “Login failed: Invalid credentials or server error” message.
Solutions:
- Double-check your email and password
- Verify the Organization name is spelled correctly (case-sensitive)
- Try logging in via the web application to confirm your credentials work
- Contact your administrator to reset your password if needed
Missing user role
Symptoms: “Missing user role” screen after login, with a message to contact support.
Solution: Your account does not have a role assigned. Contact your organization’s administrator to assign you a role (Viewer, Installer, Designer, or Manager).
Search Issues
No devices found
Solutions:
- Check for typos in your search query
- Try searching by a different identifier (name, serial number, Customer Label ID)
- Ensure you are logged into the correct organization
- The device may not yet be registered on the platform
Too many results
Symptoms: “More than 30 matches” warning banner.
Solution: Refine your search with more specific terms. Use exact identifiers like serial numbers or Customer Label IDs for precise results.
QR scanner not working
Solutions:
- Grant camera permission when prompted (check device settings if previously denied)
- Ensure adequate lighting — the camera needs to clearly see the QR code
- Hold the device steady at a readable distance
- Clean the QR code label if it is damaged or obscured
- Try manually entering the identifier from the label instead
Device Data Issues
Measurements not updating
Solutions:
- Check the Last seen timestamp — if the device hasn’t been seen recently, it may be offline
- Pull down to refresh the device details
- Battery-powered devices report at intervals (minutes to hours) — wait for the next report
- Check battery level — a depleted battery prevents reporting
Device shows as stale (dimmed)
Symptoms: Device appears at 50% opacity in search results.
Explanation: The device has not communicated for more than 3 days. This may indicate:
- Battery depletion
- Device powered off or removed
- Network connectivity issue (gateway offline)
- Device outside wireless range
Configuration command not delivered
Solutions:
- Check the Command Log on the Configuration screen for the command’s delivery status
- Commands are delivered on the device’s next communication cycle — this may take time
- Ensure the device is not offline (check Last seen timestamp)
- Verify you sent the correct command for the device model
App Issues
Camera permission denied
Symptoms: QR scanner button doesn’t open the camera; “Camera permission is required” message.
Solution: Go to your phone’s Settings → Apps → Haltian Field → Permissions → Enable Camera.
App appears frozen during login
Symptoms: Spinner showing “Initializing spaces…” for a long time.
Solution: The app is loading your organization’s space hierarchy. For large organizations with many locations, this may take a moment. If it takes more than 30 seconds, force-close the app and try again. Check your network connection.
Favorites not showing data
Solutions:
- Pull down to refresh the Favorites screen
- Verify the favorited devices are still active (check Last seen)
- Favorites are scoped per organization — ensure you are logged into the correct organization
