T8b949e/// udp must still have an associated tcp connection to detect when the connection is over.
T8b949e/// this does not apply to the server (as in rns server) as it detects that the frame is being closed
T8b949e/// udp doesn't have a connetcion so the server cannot detect that the remote server the client is connecting
T8b949e/// to is offline per say.
T8b949e///
T8b949e/// basically, the client can stop the udp connection either by the reticulum link breaking
T8b949e/// OR the process using the udp connection stops
T8b949e/// while the server only stops in the first scenario because the server cannot know if the remote
T8b949e/// server not responding is part of the protocol.
