I saw that this topic was posted 2 years ago, but I was wondering if there was another way to embed a PBI report in the government tenant to O365/SharePoint. I tried to publish to the web (Since the "Publish to Sharepoint link still isn't available) and copy the URL out and can hit it from a browser inside our network, but when I bring up the SharePoint page either using the Webpart or an embedded iframe, I get the same "no response".. the page loads but the report doesn't load.
Is there no intention to allow publish to SharePoint inside an Government tenant organization?
Thanks for your help
As I know, Power BI haven't enable the option for embed report to SharePoint for Government tenants.
You could vote this idea in here which has been submitted in Power BI ideas forum.
In addition, for your scenario, you'd better have a support by creating a ticket in Power BI support to get further help, because I don't have the environment to test.
