Qlik data transfer UI not starting properly

[jolof]

When starting the Qlik Data Transfer after upgrading it to the February 2021 release it just  shows a white window with no fields or menues. 

Is this a known issue? What is the root cause and how can we make it work again.

OS: Microsoft Windows [Version 10.0.14393]

Thank you in advance

There may be one or more of the following issues.

• The client certificate is not available from C:\ProgramData\Qlik\DataTransfer\DataUpload\certificate
• The server certificate is not available from C:\ProgramData\Qlik\DataTransfer\DataUpload\certificate
• Certificates are invalid.
• The certificate chain is invalid.
• Certificates are not present in the Windows Certificate Store.

Two ways to fix:

1. https://help.qlik.com/en-US/cloud-services/Subsystems/Hub/Content/Sense_Hub/QlikDataTransfer/trouble...
   
   if  1 does not work then
   
   2. check-in MMC for a duplicate certificate of QDT
   
   - if yes then, uninstall QDT completely
   - remove all the duplicate certificate from QDT
   - Install QDT again

Hi Akki,
Should I remove all these items?

[list if 6 certs issued to QdtClient, issued by QdtClient]

I am not able to see the image file:

What you can do is :

- Uninstall QDT 

- Remove leftover certificates of QDT from MMC

- REinstall QDT as admin

So all 6 certs issued to QdtClient, issued by QdtClient are only related to Qlik Data Transfer and nothing else related to Qlik View?

[Akshesh_Patel]

 Yes and should look like duplicate certificates..Do not delete anything except QDT.  For safety, you can make a copy of that if you want to.

Hello Akshesh,
I have removed all 6 certs, uninstalled Data Transfer, installed Data Transfer as admin and still got the white screen. Now there is only 3 certs. Any suggestion on how to solve? Any bug correction on its way with a proper error message?
Thank you in advance

Are you trying to install QDT on the same server where Qlik sense enterprise is installed, or you are installing it on a separate server?  

If you are installing on where QS server is installed would you mind check and see if these certificates are present:  Navigate to C:\ProgramData\Qlik\DataTransfer\DataUpload\certificate and confirm the following files are present:

• root.pfx

• client.pfx

• server.pfx

There should be more old certificates stored on your machine. please check all folders to make sure you delete old ones. 

Hint: check personal, trusted root, Intermediate Certification folders as well - ( computer account, current user account )

Please Note: You need to make sure , you have removed the old QDT certificates before you install it again
