I'm having the same issues. I cannot refresh my CRM Online data using oData feed. How can I delete the credentials?
To remove the credentials, go to File in Power BI and select Options and Settings and select the Data Source Settings Option. You will see the Data Sources you are using in your file and there you can Clear Permissions from one or all of them.
Hope this helps!
I cleared the permission and the connection to CRM started working, but the same issue occured again! I'm wondering what actually is triggering the issue and how can be prevented?
I was having the same issue you seem to be having. Check the Organization Service URL that you copied from your CRM Customizations Page, eg: 'https://<org>.crm.dynamic.com/XRMServices/2011/OrganizationData.svc'.
The link that was in my CRM left out the word 'Data' after Organization. I simply typed in 'Data' back in and it worked for me. Hope this helps.
