Power BI embedded in website - report not rendering

Hello there,

We have an application that renders some Power BI reports, following more less this tutorial - [Embedding Power BI in Blazor] - can’t add link, so need to google it :smiley:

When application is not routed through Cloudflare, all works fine. But when traffic goes through Cloudflare - which is how we want to approach it, it does not render. Just a blank page, no http errors, neither nothing in Cloudflare logs for this URL.

Any idea what could be a root cause of that and how to diagnose it?
