Hello! We are a game developer, and the UWP project released by our game runs under WIN10 system, and the network timeout occurs. But this problem is useless under the WIN11 system, what is the reason for this?

Hi @yu xiao ,

Welcome to Microsoft Q&A!

What version of win10 are you testing now? Can the same problem be reproduced on other versions of Win10? If possible, please provide relevant code snippets for network timeouts so that we can further check the problem for you.

Thank you.

Could you please tell us which line of code will give you time out? Also, have you tried to send the same request in fiddler to see if it will give the same behavior on the same device?

Fiddler is a web debug tool that could detect the http request sent from your device.

postman is an API tool that can be used to simulate http requests.

“var MapCfgFromCCenter = await RequestPost(url,"");”
Execution here will timeout

What does ''fiddler'' mean?

Is your app a native UWP app or a unity converted app?

Please make sure the Http request works correctly out of the app
