UWP app not working properly on other PCs except mine

UWP app is using local network to connect to a Digital Billboard. It does'n connect to Billboard on other PCs. Except mine that I built the app on that. And also works fine on a fresh windows 11 preview.
I checked the app in Firewall. And compiled with x64 and x86 with its SDKs but same result.
It seems it's missing some requirements but I don't know what things.
Thanks in advance.

Universal Windows Platform (UWP)

    Maybe try enabling the [privateNetworkClientServer][1]? By default apps can't access the local network.

    Hello, Welcome to Micorosoft Q&A,

    UWP app is using local network to connect to a Digital Billboard.

    The problem is the app enable network loopback default, If you run it with visual studio.

    If you installed the app by sideload way to other machine, please refer this document to enable app network loopback manually.
