Power BI Report Server does not show anything after loading data

Hi everyone,

I published my report which created by power bi desktop for report server.

 I can see that uploaded report on server but when I click my report to view on report server it shows nothing. I says loading data and shows me a blank page.

And also I tried to upload .pbix file to report server manually and it says "There was an error uploading your .pbix file. Verify that the file has not been corrupted and that the file extension matches the format of the file."

You can be sure I downloaded optimized power bi desktop for report server (October 2020) and I use it to publish.

Any advice?
