Error! Failed to establish connection to the server . Kindly restart the Emsigner gst emsi

Hi Roshan,

The "Error! Failed to establish connection to the server" while submitting GST returns with DSC via Emsigner is a common problem. Here are some quick troubleshooting steps you can try to fix it:

Steps to fix Emsigner connection error:

1. Restart Emsigner

   • Close the Emsigner application completely.

   • Open Task Manager (Ctrl + Shift + Esc) and ensure no Emsigner.exe or Java processes are running.

   • Restart Emsigner and try again.

2. Check Internet Connection

   • Make sure your internet is stable and firewall is not blocking Emsigner.

   • Try switching to a wired connection if you are on Wi-Fi.

3. Run Emsigner as Administrator

   • Right-click on Emsigner icon → Run as Administrator.

   • This often fixes permission-related issues.

4. Update Java

   • Emsigner depends on Java runtime.

   • Ensure you have the latest Java version installed.

   • Uninstall old versions and install latest from https://java.com/en/download/

5. Disable Antivirus/Firewall Temporarily

   • Sometimes security software blocks Emsigner.

   • Temporarily disable antivirus/firewall and test signing.

6. Check USB Token and Drivers

   • Make sure your DSC USB token is properly connected.

   • Reinstall USB token drivers.

   • Check if the token is working by trying to sign a document using other software.

7. Clear Emsigner Cache

   • Sometimes cache files cause issues.

   • Navigate to:
     C:\Users\[Your Username]\AppData\Roaming\Emsigner and delete contents.

   • Restart Emsigner.

8. Check System Date & Time

   • Ensure your system date/time and timezone are correct.

9. Reinstall Emsigner

   • Uninstall current Emsigner.

   • Download the latest version from official GST portal or eMudhra site.

   • Reinstall and retry.

10. Use Offline Signing Mode

    • In some versions, there’s an option to sign offline.

    • Try that if online signing keeps failing.

If still not working:

• Try on another computer.

• Contact Emsigner/DSC vendor support or GST helpdesk.

• Check for any GST portal downtime or maintenance announcements.
