Azure DevOps - Unable to connect

[AndyDev]

I am trying to connect to Azure Devops, a few weeks back I managed to get a report working and this version is still ok. Now I try and use the same credentials , organisation and team project in the settings but I keep receiveing the error below when I use get data 

Unable to connect

We encountered an error while trying to connect.

Details: "The downloaded data is HTML, which isn't the expected type. The URL may be wrong or you might not have provided the right credentials to the server."

It is really strange that the existing report works fine but if I try and change the connection settings on the working report it also fails with the above.

Does anyone have any ideas I can try?

Hi @AndyDev 

Which connector in Power BI do you use?

Please check the documents below:

using the Azure DevOps Power BI Data Connector

Power BI Integration with Azure DevOps

Update to lastest version,

Open a new blank Power BI file,

Clear the permission for the data source(Edit queries->Data source setting-> find Azure DevOps source->clear permission),

reconnect to data source using methods above.
