Yes, those applications were good before. Until a certain update of xbox, uninstalling the application and reinstalling it again will encounter this problem.

Have you checked the output logs on the Xbox during the connection attempts? Also, it may be worth verifying if any recent Xbox updates adjusted the network handling capabilities, as this could explain why the connections fail after a certain update. Additionally, could you confirm whether other devices on the same network can connect to different ports on the Xbox, or if it's specifically port 22112 that fails?

After that, I reset the system on another Xbox and reinstalled the app for testing, and the problem could be reproduced each time.

I've basically tested all possible scenarios. It's not an issue with the code, local network, or development tools.

It might be worth checking if any specific firewall settings on the Xbox are blocking the StreamSocket connections since the error occurs after a recent update. Additionally, examining the output logs during the connection attempts could provide insight into what might be failing during the network handshake process.

Thank you for your reply. The xbox system does not have firewall settings. I have tried many ways to analyze packet data and logs. The final conclusion is that the xbox system blocks uwp network rules, and the use of xdk is not affected.
