So what’s a problem?

Doesn’t look like a problem to me. There is nothing for the network server to do, going by the gateway bridge logs.

Basic communication protocol between Lora gateway and server
=============================================================


1. Introduction
----------------

The protocol between the gateway and the server is purposefully very basic and 
for demonstration purpose only, or for use on private and reliable networks.

There is no authentication of the gateway or the server, and the acknowledges 
are only used for network quality assessment, not to correct UDP datagrams

Although section 5 of the above uses the word “server”, unless there is data waiting for the gateway, it is in effect Gateway ---> Gateway Bridge.
