I am Commercial Tax Inspector in Kerala

I have succeeded after various steps by this method.

1. I have first uninstalled all DSC token softwares from my PC.... like Trustkey, ePass, WD Proxkey etc by going to Control Panel > Programs > Programs and Features >Uninstall Program.

2. Secondly I have uninstalled emSignor software.

3 Then Updated 'Chrome' Browser with latest version from their website

4.Then Go to Chrome Settings menu by

(There may some slight variations in Chrome Menus in different versions)

   In Chrome : Settings>Advances Settings /Show Advanced Settings(menu seen at the bottom)  > Content / Content Settings  > Java / Java Script/Java Settings > Exception / Manage exceptions > Then in the web site entry column / Host name Pattern entry column ( > Click Add Button ( if shows - in some Chrome versions don't have this 'Add' button) Then......

replace the '' with the following address

and dont change the status as 'Allow' ( If it shows status as ' Block / Blocked' change to 'Allow' / 'Allowed' )

press "Enter' key.  Then 'OK'

5. Install latest version of emSignor from GST website by logging with user id and password  from the link provided at Update / DSC menu on Dash Board .

6. After installation 'Right click' on the desktop icon of the emSignor and select 'Run As Administrator'.

7. Then insert the DSC Usb Tokens and install the concerned software related to the DSC issuing Authority.


It may be successful for such issues

First thing whatever troubleshoots windows operating software provides are useless and similarly this application does no wonder in providing troubleshoot for resolving your issue of estalishing connection.

This question was already asked, DSC issue while signing GST registration application but we could not reach on a solid answer.

My answer will cover your following questions:

  1. failed to establish connection to the server . kindly restart the emsigner click here to troubleshoot.
  2. failed to establish connection to the server . kindly restart the emsigner
  3. failed to establish connection to the server gst
  4. emsigner errors

Since there is no working solution yet, let us first try to check whether system is updated and all settings are done as per system requirements specified on GST website.

As per information provided on website check following settings on your system:

  • You are using Internet Explorer 10+/ Chrome 49+ or Firefox 45+,
  • Do not disable javascript, CSS or cookies on your browser,
  • You should have a valid DSC of level 2 or level 3 issued by a recognised CA ( Certifying Authority )
  • You should have Java 1.6 JRE 1.6.0_38+, Java 1.7, Java 1.8
  • Any one of the these ports should be free 1645, 8080, 1812, 2083, 2948

I think from above list of system requirements most of the users will have trouble with signing using a DSC due to either old browser or Emsigner.

To resolve the issue first update your Java and make sure you have recommended Java versions.

If Java and browsers are updated and latest, then issue will be due to Emsigner using wrong port or port is not free.

In my office, I faced this problem multiple times and noticed that I had to restart my computer to get the Emsigner work.

My observations are that non availability of port is the main reason for Emsigner not working properly.

At the time of signing, normally following applications run on computer:

  • Tally with multiple users or Tally running on network. Most of the time tally is the reason for issue, if you are using network tally then make sure that port used by tally is not same as port used by Emsigner. You need to close tally to Emsigner work.
  • Disconnect with network computers to avoid multiple computers using same port connected to your system.
  • Applications such as Outlook, Antivirus also cause issue.

Finally my conclusion is that to resolve issue, restart your system and do not open any application running on network to avoid port conflict.

    In first place why they are using Emsigner, GST department should solve the problem faced by tax payers. They should have adopted what Income Tax portal is doing, Either they should have given a separate Java utility just IT department or allowed signing directly on GST portal how MCA is doing. - GST Payer
    Technology is advancing at a very fast speed. We have to catch it or we will be obsolute whether its in our practice or general life. But I think this Emsigner thing is really painful and either Emsigner come up with a solution or government should release some other application. - Pulkit Sharma
    Advancement in technology is a totally different thing to discuss, here tax payers and consultants are forced to waste their entire day for job which should not take more than 2 minutes. - GST Payer
    Its same everywhere, thanks to IT department they have solved the DSC issue forever but still cannot use their appliation on Apple computers. Digital governance advertised by GOI will fail if GST is going to follow the same steps of MCA. Whether DSC on MCA or GST, both are making life difficult for consultants and practicing professionals. Opportunity cost in handling these issue is alarming high and GST is tax which will be far more adopted then few using MCA website. - Pulkit Sharma
    This is the final solution I think available all over internet. It worked for me. - Rahul Rai
    If this is not working refer answer by Shijoy James with full instructions. - Rahul Rai

 Answer provided by Pulkit is explained very well.

However to quote in a simple language, you can do following things to get DSC in working mode.

  1. Update your Java and make sure you have JRE installed.
  2. Install Emsigner in administrative mode and even use in admin mode.
  3. Install your DSC drivers. Remember different DSC tokens have different drivers.
  4. Update your browser.

Try now every thing should be working.
