Hi @Lim Sheau Shin (NCS) ,
What version of SSRS are you using?
I tested locally and everything works fine.
I exported the report in EXCEL format successfully.
The web service URL is the backend, used by the frontend (and can also be used in its own application), when you deploy reports from tools like report designer/report generator, you will need to use the backend web service URL. For just exporting/managing reports, you can use the web portal.
Best Regards,
Joy
