Okay. I also just realized that my application was not listed in
"allowed" list in the Windows Firewall config. And strangely it didn't
show up the popup when I started it again. Maybe I accidently pressed
the wrong button then. Adding the app to the "allowed" list also fixed
my problem.

So it looks like when an application is not marked as "allowed",
Windows will only forward incoming packet to the application only when
the application has recently sent outgoing packet using the socket.
Interesting, as I thought Windows will refuse to send/receive packets
