OData issue using Power BI API
Final managed to solve this issue.
I had to delete and re-add the SPNs for the ReportServer Service account. The OData connectivity now works.
Why? Don't know but it works.
Hmm, when I use an OData data source with Windows auth and domain\user the test button (and scheduled refresh) works for me. If I remove the "domain\" prefix it does not work, but I'm assuming that the server was trying to authenticate the user as a local account instead of a domain one.

Curiously though if I copy the OData url directly into the browser address bar, it correctly gives me the .json file to download.
When you paste the URL in the browser are you logged in as the same user which you are trying to test? Or are you running the browser under your account? To test this properly you would either need to log in as the user you are trying to save against the data source or use "runas" to run the browser as this user.
If this fails it probably means this users has no rights to the folders in the PBIRS portal and you would need to go into the manage folder options and then into the Security tab and make sure this user has at least "Browser" rights.
Yeah, it's a puzzle...
I get the same error using my domain/user login credentials in the test connection box, which is why it's confusing that the .json file downloads from the browser.
My user account is in an AD Group with Content Manager rights on the whole PBIReport Server.
May have to get the SQL team to SSIS these queries into a db rather than using the api... which would be a shame.
I'm struggling to think what else we can try.
There is a long shot that this might just be a bug with the "Test" button, so maybe try saving your credentials anyway as a temporary test (since we know your account definitely gets the expected json result) and see if you can then run a scheduled refresh.
And the other thing that is worth checking are the PBIRS logs, maybe they might have more information that will give a hint as to why this is not working.
It's also worth checking how the service account for PBIRS is configured - is it using a domain account or something like NetworkService which would have permission to authenticate accounts against AD?
Hi
I've tried saving the connection and scheduling - same result
Checked the log files - nothing conclusive in there.
Developer tools (F12) in IE (yeah we're stuck with IE) gives this error in the response body:
{ "@odata.context":"http://<MyServer>/PBIReports/api/v2.0/$metadata#Model.DataSourceCheckResult","IsSuccessful":false,"ErrorMessage":"Log on failed. Ensure the user name and password are correct." }Good point about the service account. It's set up with a Domain/Username account not a Network Service account. Not sure how to check the permission to authenticate part...
Thanks again for being a second set of eyes on this...

That should not be the issue then. We normally use domain\username for our service accounts too. This means that the account should definitely be able to connect to your domain. (I think the service account would only be an issue if it was setup with LocalSystem or something like that).
Maybe you need to ask your domain admins, see if they can see authentication failures and help figure out what is going on here.
