RG1XX keeps disconnecting

Hi there! Im working with Laird Sentrius RG119 Gateway and a RAK7200 node. Network works fine for a while, but then Gateway enter on a Connect-Receive Gateway Status-Disconnect bucle ending up in a connection lost. I configured the RG1xx with CUPS and LNS, as recommended here Can't get Laird RG1xx Basics Station Forwarder working with TTN - #15 by jakymiwm but problem persist. Am I missing something?

Hi,
I have already created end device-lorawan gateway-thethingsnetwork-mqtt-nodered-influxdb-grafana setup via private network and succeeded. I can collect time series data. When I connected to private network, wifi and lora was connected. But when ı connected via ethernet lora was not connected. But ı want to collect data constantly so ı should use ethernet. How can ı achieve this problem? everything is okey when ı use my private network. Also, I am working with raspberry pi 4.Thank you for your helps.

Only if the WiFi network at the gateway location isn’t on 24x7. If there is permanent WiFi coverage there is no reason not to us

So why do you post in a topic that is totally unrelated to RPi 4 based gateways?
