Unable to read data from the transport connection:



So aver the last two to three days I am having a varieity of issue with my Odata connection to CRM online. At first it was complaining with teh following error when trying to refresh the datasource:


"Data response result. Error: The property 'bizmap_businessid_businessunit' does not exist on type 'Microsoft.Crm.Sdk.Data.Services.BusinessUnit'." - So i assumed that a field that was part of a dataset had been changed, so i rebuilt the query in PowerBi Desktop (testing the refresh with no error" and republished.


Has the same issue again, which is odd as i tested the refresh on the desktop publisher with no errors.


Then forced a refresh again a few hours later and get a different error:

"Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host."


The odd thing is that this all worked fine for about 1 month up until 2 days ago.


Does anyone have any ideas.


Thank you in advance

This issue happened with my while running several Dataflows from datasource folder in Onedrive or sharepoint, it kind of make sense that the source folder serve only one connection at a time, i resolved it by running schedual refresh time of my dataflow in a way that allow not more than two dataflow connections to hit the source folder at the same time, depends (offcourse on the datasize) leaving a reasonable gap to (30 Minutes) between every connection. it might not be a perfect solution but it gets the job done eventually 🙂

Hey, just wanted to add that we're getting this error as well.  Are there any other logs we can check in PowerBI to get more of an idea of what's going on?  If any find a solution can you pls post.

Thanks heaps.

Hi @saunders,

Yes Saunders, I have used fetchxml as part of web query to extract data. I have also submitted a blog for same.

However it is pending for approval from Microsoft.




Hi I'm also eager to read your blog posting to resolve this problem. Did your blog posting ever get approved or can we see the info on some other non MS approved blog ? Please do let us know.


Trying to resolve a Power BI desktop connection to Dynamics 365 online instance using:

Source = OData.Feed(""),
ContactSet_table = Source{[Name="ContactSet",Signature="table"]}[Data]


Will be checking logs, fiddler etc....but still keen to read your blog.

Hi @peterg_intervat

Have you got the solution ?



Hi there


No solution to this yet. This problem comes and goes. Which sadly impacts the business case to make it a permanent solution. I am not sure if it has to do with the fact that the feed timesout. It would be awesome if the feed would be more "real time" 🙂

Thank You for information !

I am also using CRM Online. Now I suspect, CRM online can also be possible suspect for problem.

Do we have setting where CRM online closes the connection ? I am not CRM online expert but do you have any idea

Hi @peterg_intervat,

I am unable to find any acess button or functionality for providing you access.

Seems Power BI team has not reviewed the article yet. It is in my staging area and has not been published to all.

I will post again on this forum when the blog gets published.



I'm getting the same error for the past two days even though mine was also working fine up to then.

Hi @solaris_rapido

Has your issue been resolved and how ?

I am facing same error and not getting a hint.
