Looks like network issue.

Try these things:
- are you running tcpdump on the correct interface?
- can you ping or connect to some open ports there (e.g
it might have ssh open)
- try running 'ip r'. Does it show a specific route for

There can be cases where an app (e.g. FR) can receive and send udp
packet to a host, but it never even got to the correct interface. In
which case ping or other connectivity test should fail as well.
