Embed Report Not working on our Front end Application

Hi Community members!

We are using Power BI premium user and created reports. Reports are present on our Power BI service and working fine.

We have embedded these reports in our React JS application using reports' embed code. In our local machine when we run our react js code, reports are loaded accurately after signing in to Power BI service.  (We have not used Power Bi APIs to embed reports, we are using reports embed code and signing on Power BI service)

But, when we hosted our applicaton on AWS then we are getting option to sign in but sign in is not working fine and can't see the reports in our application.

Does anyone have encountered same issue and have any idea how this can be fixed.

Regards,
