Due to changes in the way reply URLs are handled via Azure App Registrations, you will need to make sure you have adequate reply URLs configured.
Please follow the steps below.
From the Azure menu, select ‘Azure Active Directory’.
Then click on ‘App Registrations’.
Use the search box to locate the app registration for your Enterprise BI Portal.
Click on the app registration to open it.
Go to ‘Settings’.
Click on ‘Reply URLs’.
Ensure that you have the following three reply URLs as shown in the screenshot and the below table.
Make sure to replace <my.site.name> with the actual site name of your BI Portal.
Once completed, move to the next version, or follow the steps under Running the Upgrade to install your upgrade.
