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.

These work with no issues in the Desktop on the server, but when I save the dashboard to the Power BI Report Server, when entering in my windows credentials I get a 'Cannot Connect, Login Failed...' type of error message.
What format are you using for your username. Have you tried entering it as <domain>\<username> ?
Hi
Yes: Domain\Username
Username has db_datareader on the PBIReportServer DB and local admin rights on the server itself.

So if you are using the OData url that user does not need any driect rights on the PBIReportServer DB or the server itself.
It's not entirely clear where you are getting is error from. I'm assuming that you have successfully uploaded your report to the server and you are getting this error in the Manage > Data Sources page - is this correct?
What authentication option have you chosen - it should be "Windows Authentication".
I just double checked this on my server and using Windows Authentication and the Domain\Username format worked for me and I was able to schedule a refresh against the http://<MyServer>/PBIReports/api/v2.0/Folders endpoint.
Thanks for looking/taking an interest...
Yup, using Windowss Authentication, and getting the error from the Manage > Data Sources > Test Connection. (I'm copying and pasting the password from our password manager which works successfully with SQL queries...)
Curiously though if I copy the OData url directly into the browser address bar, it correctly gives me the .json file to download.
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.

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.
