Diagnostic Checklist
If the LamaniSync extension status badge is not displaying green, check these four essentials first:
- Is the clinic workstation connected to the internet?
- Is the clinic CMS tab open in Google Chrome and actively logged in?
- Is the LamaniSync extension icon pinned to your Chrome toolbar?
- What error code is shown in the extension popup?
Error Code Reference Guide
| Error Code | Meaning | Remediation Steps |
|---|---|---|
ERR_TOKEN_EXPIRED | The pairing token was generated over 15 minutes ago. | Return to LamaniHub, click Generate New Token, and pair within 15 minutes. |
ERR_HOST_PERMISSION_DENIED | The user clicked "Block" or cancelled the origin permission prompt. | Right-click the extension icon → Manage Extension → Site Access → Select On specific sites and add your CMS URL. |
ERR_MUTEX_TIMEOUT | Another workstation currently holds the active write lease. | This is normal multi-workstation behavior. The current workstation will remain in standby until needed. |
ERR_CMS_SESSION_EXPIRED | The front-desk user was logged out of the CMS portal. | Re-authenticate into your clinic CMS in the open browser tab. |
ERR_READBACK_FAILED | The appointment was written, but verification failed to find it in the calendar. | Check if the selected time slot was manually blocked in the CMS. LamaniHub automatically alerts front desk. |
ERR_WEBSOCKET_DISCONNECT | Temporary internet drop or network proxy interruption. | LamaniSync automatically reconnects with exponential backoff (1s, 2s, 4s, 8s). |
Preventing Chrome Tab Discarding (Memory Saver)
Modern versions of Google Chrome feature an aggressive Memory Saver that suspends background tabs after periods of inactivity. If staff leave the CMS tab in the background, Chrome might put it to sleep.
How to Keep Your CMS Tab Always Active:
- In Chrome, open settings by visiting:
chrome://settings/performance
- Look for the "Always keep these sites active" section.
- Click Add.
- Enter the domain of your clinic CMS (e.g.,
live.dentrixascend.comor*.eclinicalweb.com). - Click Add.
Now Chrome will never suspend or discard your clinic calendar tab, ensuring 24/7 background availability.
Antivirus & Web Shield Whitelisting
Certain enterprise antivirus suites (such as Kaspersky, Norton, or Bitdefender) feature SSL inspection that can interfere with secure WebSocket handshakes.
If your connection drops repeatedly:
- Add
*.lamanihub.comto your antivirus SSL Exclusion / Web Shield Whitelist. - Confirm that your workstation clock is synchronized to internet time (NTP). An incorrect system clock will cause WebCrypto certificate validation to fail.
