API closess conection after ReportSubmitRequest

Question

I am currently trying to request a AdPerformanceReport using my own application and I am using the PHP SDK as a reference.

Requesting a report with the SDK works but with my app it does not despite sending basically identical xml strings. Both versions post to "https://reporting.api.bingads.microsoft.com/Api/Advertiser/Reporting/v13/ReportingService.svc?singleWsdl"

This is the error I see when I use my APP:

Post "https://reporting.api.bingads.microsoft.com/Api/Advertiser/Reporting/v13/ReportingService.svc?singleWsdl": read tcp MY_IP->168.61.2.231:443: read: connection reset by peer

I would love to know the reason for this error.

Request xml taken from the SDK:
