Qlik data transfer UI not starting properly

jolof — Fri, 02 Apr 2021 08:50:43 GMT

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:

https://help.qlik.com/en-US/cloud-services/Subsystems/Hub/Content/Sense_Hub/QlikDataTransfer/troubleshooting-qdt.htm

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

Best

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?

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

Hello
QS is not install, but QV is installed on the same server.
server.pfx and client.pfx are present but not root.pfx

I uninstalled Data Transfer again.
All qdt certs om local user account and computer account were then removed.
Data transfer was then installed as admin. Data Transfer is still not working.

root-only be there if you have QSE installed.

In addition, This is happening because one big change is due to identified potential security issues, the introduction of certs with QDT. The consequence if installing on a machine with QSEoW QDT needs to be installed with the Qlik Sense service user, enabling QDT to get certs that QSEoW is using to reuse in order to avoid a conflict or regenerating them.

YOu can try installing the QDT as a Qlikview service user. was the October version works fine?

jolof — Wed, 24 Feb 2021 21:54:38 GMT

QSEoW is not installed on the machine in question.
I don't have access to the user details of the Qlikview service user and I don't agree on installing QDT with a user meant as service user.
October version was fine but we are having issues with the file size limit. Also if there are identified potential security issues we prefer the February version.
We also restarted the machine but it didn't help.
Is the co-existence with the Qlikview service the root cause to the problem we have with QDT?

Please refer to the attached document and see if that resolves the issue.

Thanks, will do it on Monday. Just a question, when it says "Restart the server" does it really mean the whole machine or just the service?

The whole server

Re: Qlik data transfer UI not starting properly

jolof — Tue, 02 Mar 2021 07:52:20 GMT

I went through the workaround document and restarted but still get a white screen, but I guess the service is OK as it doesn't get the upload error in the log. Two exceptions though: service is started with LocalAccount so I can't log in and run remove script with the same user and I never added the TLS cipher suite in the server group policy as I'm not Windows Administrator on Windows level and wasn't able to contact Windows support.

Any timeplan on correction?
