error in establishing connection with traces websocket esigner. please ensure that websigner setup is installed and service is running on your machine and there are no proxies enabled on the browser while doing dsc activities

This error occurs when the TRACES WebSigner utility cannot communicate with your web browser. This is typically due to an outdated Java version, the service not running with administrative privileges, or browser security settings blocking the connection.

Quick Fix Steps

  1. Restart WebSigner as Admin: Locate the emSigner or WebSigner icon on your desktop or taskbar, right-click it, and select Run as administrator.
  2. Verify Java Version: TRACES requires Java 8 Update 162 (32-bit) to function correctly. Even on 64-bit systems, the 32-bit version of Java is often required for compatibility.
  3. Disable Browser Proxies: Ensure no VPN or proxy is active. In Chrome, go to Settings > System > Open your computer's proxy settings and ensure “Use a proxy server” is turned Off.

Detailed Troubleshooting

If the quick fixes don’t work, follow these steps in order:
  • Reinstall Cleanly: Uninstall any existing versions of Java, emSigner, and your DSC drivers from the Control Panel. Restart your PC before reinstalling.
  • Download Latest Utility: Log in to the TRACES Portal, navigate to Downloads > Requested Downloads, and download the latest TRACES WebSigner Setup V 2.0.
  • Whitelist the Port: Ensure your firewall isn’t blocking Port 1565, which is used by the WebSocket. You can check this in Windows Defender Firewall under “Allow a program through Windows Firewall”.
  • Browser Security Bypass: Open a new tab in Chrome and enter https://127.0.0.1:1565. If you see a privacy warning, click Advanced and then Proceed to 127.0.0.1 (unsafe). This allows the browser to trust the local connection required by the signer.
  • Add Java Exceptions: Open Configure Java from your Start menu, go to the Security tab, click Edit Site List, and add https://127.0.0.1:1565 and https://*.tdscpc.gov.in.
