Issue with embed a report in a public website

We are trying to embed a report in a public website that is using an existing Power BI dataset. After I go to file-> "publish to web" and click on "create embed code" on the last window when I click on "publish" I see the text "Creating a code..." for like two seconds and it then fades off and nothing happens. We have embedded other reports in public websites without any issues. The only difference I can see for this report is that it is using an existing Power BI report. I have Admin (Owner) access to the Power BI dataset I am using in that report.
