HTTP Post do not success on Windows Phone 8.1 but on Windows 10 Phone!?


I am working on a Windows Phone App. To do a login a send the data with $ This works great on a Windows 10 Phone (Windows Universal) an iOS and Android but will end in a STATUS 0 on a Windows 8.1 Phone (Lumia 640).

Any ideas why?

Hi, I’m working with wp8 too, and I have not problems. Can you show a bit of code from client and back/api rest?
