Troubleshooting Pairing & Connection Drops

Diagnose and resolve connection errors, ERR_TOKEN_EXPIRED, ERR_HOST_PERMISSION_DENIED, Chrome tab sleep settings, and network drops.

Diagnostic Checklist

If the LamaniSync extension status badge is not displaying green, check these four essentials first:

  1. Is the clinic workstation connected to the internet?
  2. Is the clinic CMS tab open in Google Chrome and actively logged in?
  3. Is the LamaniSync extension icon pinned to your Chrome toolbar?
  4. What error code is shown in the extension popup?

Error Code Reference Guide

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:

  1. In Chrome, open settings by visiting:
   chrome://settings/performance
   
  1. Look for the "Always keep these sites active" section.
  2. Click Add.
  3. Enter the domain of your clinic CMS (e.g., live.dentrixascend.com or *.eclinicalweb.com).
  4. 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.com to 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.
