Invalid user specified error

Hi NarKamat were you able to find a solution? I used the Adobe native connector but I had some issues. As a workardound, maybe you can test your connection using a 3rd party tool. I've tried windsor.ai , supemetrics (which doesn't has PBI as a destination, so you first have to export to Google Sheets and then export to PBI) and funnel.io. I stayed with windsor because it is much cheaper so just to let you know other options. In case you wonder,  to make the connection first search for the Adobe connector in the data sources list:

Then, you should enter your Adobe credentials to make the connection. After that, you'll see a preview of your data where you can select the fields you want to see in PBI. 

Finally, you just have to choose PBI as destination and copy and paste the url that will appear there in PBI desktop --> Get Data --Web > --> Paste the link
