Cannot Connect Server on Android/MAUI Blazor Project

Hello All,

I have created Server Android Blazor MAUI Project and bound and started as Foreground Service.

I cannot connect to server from pc client. I tested with other andorid mqtt broker apps and can connect but not with my project app. So I am sure tablet is accessible from outside.

Any idea and help appreciated. Thanks.
