Unable to send the Reports to mails from Portal using RSRT

Hello All,

We have BI JAVA 7.4 with BW ABAP 7.31 which are running on  Windows environment.Recently we configured Bex and Broadcast which are working fine. Email/Broadcast has sending out without issues by using t-code RSRD_ADMIN.

When using t-code RSRT and by providing with a report, when we navigate/execute JAVA WEB icon to see output in portal,output is seen in the portal and issue is when we try to send e-mail from that same page,there is a button for sending out mails by clicking on SEND button, we are not able to send mails, the new screen/window will pop up and keep on spinning/rendering, but unable to get the output.Kindly check the attached.

Please Suggest

Thanks
