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

Hi aill, 

Since some time now I've been running into issues to connect to Sharepoint and Onedrive urls in Power BI Desktop.

After I publish the report to the service the refresh works fine, so it seems to be something particular to my device.

The device doesn't have any connectivity issues outside Power BI nor to other data sources. Also I didn't make any changes, suddenly this issue appeared for all sharepoint / onedrive connections.

I have tried many things until now, applying solutions from this forum and also rasied a ticket with Microsoft Support for O365, but they didn't want to help as it did not seems to be a problem with my tenant / account...

The issue

When trying to access data on sharepoint via Power BI, the error is not always the same, nor does it occur at the same point in the process.

Sometimes an error already occurs when I try to authenticate, the login.microsoft url doesn't load and states an error about TLS settings. If I then retry to sign in a couple of times, at some point the tool will let me authenticate (30% of the tries).

However, on report refresh in Power BI Desktop, I will get this error for all sharepoint queries in that report (100% of the time).

Looking into the Power Query editor, I see that the data is sometimes loaded normally, so the authentication did pass and data is returned, no errors whatsoever.

However if I then click 'refresh preview' the query result will sometimes suddenly return the same error as with the report refresh:

Less often, I get the long long error statement below this post. If I then hit refresh preview a view times more it will at some point again show my data as normal. How can that possibly be???

As mentioned I already tried a lot of things:

- Uninstall third party security software + turn off firewall entirely

- Uninstall and reinstall network adapter driver

- Try different MS accounts, connecting to different Sharepoint tenants

- Use a different browser, clear browser cache

- Reinstall browsers, reinstall Power BI Desktop

- Try a different device: with a different laptop, I can connect just fine, thus seems to be a device issue but I didn't make any changes. Error occured 'out of nowhere'. 

- Play around with TLS settings, eventhough they were already at defaults (TLS1.0, 1.1, 1.2 checked, SSL 3.0 unchecked)

However, all these solutions didn't work. Also, do note that the device doesn't have any other connectivity issues, and the data is sometimes shown in the PQ editor, just the full refresh never works.

As you might understand, I have already put a lot of time into this issue and tried all sorts of solutions.

However, I really need this solved for my work with clients, I'd rather not throw away this otherwise perfectly working laptop.

Is there someopne who knows of different causes / solution or ideally how I can get a support call with someone who might know more about this? As mentioned I tried with MS 365 as I have a subscription, but they turned me down.
