Even 2 same Windows bedrock version cannot see each other. (java version is ok)

We have multiple devices, Windows PCs, iPads, iPhones, all devices(including windows) can see worlds created on iPads and iPhones, but no device can find worlds created on windows. It's been working for a long time, but had this issue lately. 

Since Windows can join games on iPad and iPhone, and Windws java version can also join each other, which means network is working correctly. We cannot locate the reason why no device can join game on Windows bedrock version, the created world was not showing on any other devices' LAN game list.
