Qlik DataTransfer - not able to create a data connection "could not create connection"

[Carl_Hunter]

Hi, getting an error below when trying to connect to an ODBC driver. I've also tried other connection types i.e. SQL Server, with the same error 

I've checked the logs (C:\ProgramData\Qlik\DataTransfer\Log\DataUploadService), and the following is reported:

24 20210706T202138.755+0100 localhost 4.0.0 Global INFO Data Upload Service listening on: https://127.0.0.1:5505

at async createConnection (C:\Program Files\Qlik\DataTransfer\DataUploadService\index.js:471:90781)

I've tried rebooting the server, stop/starting services to no avail 

Any ideas Qlik guys and gals?
