RPI Local Server Gateway Never Seen, i'm receiving data on chirpstack-gateway-bridge

i configure chipstark v4 on my rpi, i did everything in the tutorial, the data is seen by chirpstack-gateway-bridge, but in web browser, after adding gateway, it always says never seen.
With chipstark v3 on the rpi, i manage to do it all, i decided to try with v4, because of documentation and recommendation from people in this forum.

Here are my steps from a clean raspbian partition

	-sudo apt install \
              mosquitto \
              mosquitto-clients \
              redis-server \
              redis-tools \
    -sudo -u postgres psql
                Inside the prompt:
                -- create role for authentication
                create role chirpstack with login password 'chirpstack';
                -- create database
                create database chirpstack with owner chirpstack;
                -- change to chirpstack database
                \c chirpstack
                -- create pg_trgm extension
                create extension pg_trgm;
                -- exit psql
	-sudo apt install apt-transport-https dirmngr
	-sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 1CE2AFD36DBCCA00
	-sudo echo "deb https://artifacts.chirpstack.io/packages/4.x/deb stable main" | sudo tee /etc/apt/sources.list.d/chirpstack.list
	-sudo apt update
	-sudo apt install chirpstack-gateway-bridge
	-sudo nano /etc/chirpstack-gateway-bridge/chirpstack-gateway-bridge.toml
                event_topic_template="au915/gateway/{{ .GatewayID }}/event/{{ .EventType }}"
                command_topic_template="au915/gateway/{{ .GatewayID }}/command/#"


	-sudo systemctl start chirpstack-gateway-bridge
	-sudo systemctl enable chirpstack-gateway-bridge
	-sudo journalctl -f -n 100 -u chirpstack-gateway-bridge
	-sudo apt install chirpstack
	-sudo nano /etc/chirpstack/chirpstack.toml
-sudo systemctl start chirpstack
-sudo systemctl enable chirpstack
   	-sudo journalctl -f -n 100 -u chirpstack

Configure lorawan gateway:
On web browser enter  gatewayIp:8000
User: root
Pass: Dragino

Go to lorawan: semtech udp

Server Address is the address of the rpi

On web browser:
Connect to  localhost:8080

Add gateway  https://www.chirpstack.io/docs/guides/connect-gateway.html
  Add device  https://www.chirpstack.io/docs/guides/connect-device.html 

Here is the result of : $ sudo journalctl -f -n 100 -u chirpstack-gateway-bridge

I remember that on v3 you have to configure somthings on network, but here i can’t seem to find any other configuration i must do before configuring gateway
Gateway configuration on api.

also, i created a python script to subscribe to topic and see data:

Could the problem be with chirpstack-network-server?
in the guide for v3 you have to add and configure this manually, and then on the web api you have to add the newtork server, i don’t see any of that on v4

Can I take a look at chirpstack-gateway-bridge.toml?

Hello nicoHydro, I was wondering if your problem is fixed now, and if so, what steps did you take? I have the exact same problem and I’m stuck in this stage.
Thank you in advance.
