Unexpected error: The underlying connection was closed: An unexpected error occurred on a send

Hi Power Bi community.

I´m aware that this is a known topic by Microsoft support. But I wanted to know if you have solved this problem by your own or if there are any updates from Official Technical Support.

The general statement of the problem is:

"I´m creating data sources from Sharepoint Folder or ODATA Sources and I make the correct connections, but suddenly when I refresh the data or after a few days a problem appears: Unexpected error: The underlying connection was closed: An unexpected error occurred on a send; followed by a huge amount of text. The main problem here is that there is no typing error, null characters or error rows, it is a pure connection issue that you cannot fix by your own"

Solutions that I have tried:

- Uninstall and Install Power Bi Desktop (several times).

- Installing the Web Version of Power Bi Desktop (avoiding the Microsoft Store Version)

- Cleaning the Data Cache in Power Bi Options and Settings.

- Deleting the whole Query and creating a new one.

- Deleting all my current credentials and carefully capture them again.

- Changing the API VERSION from 15 to 14.

Actions items for the community:

- Have you had this problem in any of your files?

- Have you solved this problem making different connections or by another way?

- Is this an open topic or there is a Microsoft Support Official Solve for this issue?

Thank you in advance for reading this topic, I hope that this could be useful!

Regards 🙂
