Network Communication On Exported App doesn´t work

Using multiple instances of gamma (1 sender, 1 receiver), the communication between instances work fine,
but when i use the exported version of them, the communication seems broken.
Sender and receiver apps are on the firewall exception list.
Am i missing something?

by the way i’m using vvvv gamma 2020.1.7

what networking protocoll are you talking about? could you best-case provide a patch that demonstrates the issue?

i’m using this pattern, provided by Natan in the Model, Runtime workshop

I’ve ported the app to Gamma 2020.2.2, and it works
