On EVERY .pbix file when I go to query editor: "Underlying connection was closed: an unexpected err"

[apmulhearn]

EVERYTIME I open a .pbix file to make a change, I have to re-authenticate my Microsoft credentials for EVERY data source, and then I end up receiving the below error.

I am the ONLY report author, the global admin for Microsoft at our firm...I have no idea what is going wrong here.

Hi  @apmulhearn ,

Make sure that your data source settings are correct and that the credentials you’re using are valid.
Ensure that you’re using the latest version of Power BI Desktop. Sometimes, updating to the latest version can resolve issues.
This issue might be resolved by enabling the Fast Combine feature within Power Query. You can do this by going into Options => Project Options => Enable "Allow combining data from multiple datasources."

Best regards.
