When I upload the built .MSIX or .MSIZUPLOAD package to Microsoft Partner Center, it gives an error even without uploading.

Local PC validation is passed. I have associated the app with the store as well.

eMS_Error1

What could be this error and how can I solve this?

Thanks much.

    Issue is resolved. Using Fiddler logs, it turns out https://upload.xboxlive.com site falls under Games category and blocked by our organization
