Chirpstack network server refuses connection

ChirpStack Network Server
1

Hello, I’m trying to add my NS, but everytime I try to add it, I get this error:

context deadline exceeded (code: 2)

In docker console it looks like this:

My NS config:

This is what I put into add fields:

image
image1632×505 28.4 KB

This happens even If I use default NS config, only thing I have changed is the AS config where I use different port, because I use port 8080 for other website

What am I doing wrong?

Since you are using Docker, one possibility is that 127.0.0.1/localhost (as shown in your configuration) refers to the Docker container itself. If AS runs in a different container, you need to specify the DNS name of the container running the NS.

3

I think they run in same container. I just ran docker-compose up. And how do I find out what the DNS name is?

4

This goes beyond Chirpstack, but is related to Docker.

Usually, a Docker container contains only one service.
Docker Compose orchestrates the deployment of Docker containers, so you probably started multiple containers.

You need to look at your docker-compose.yml file to know what name(s) were given to the NS container, for the network that it shares with the AS. Yes, they should be on the same network too.

5

So Into the field of network server server (in web interface) I should put dns name:port intead of localhost:port?

This is my docker-compose.yml


version: "3"

services:
  chirpstack-network-server:
     
    image: chirpstack/chirpstack-network-server:3
    volumes:
      - ./configuration/chirpstack-network-server:/etc/chirpstack-network-server
    depends_on:
      - postgresql
      - mosquitto

  chirpstack-application-server:
    image: chirpstack/chirpstack-application-server:3
    ports:
      - 9090:9090
    volumes:
      - ./configuration/chirpstack-application-server:/etc/chirpstack-application-server
    depends_on:
      - chirpstack-network-server

  chirpstack-gateway-bridge:
    image: chirpstack/chirpstack-gateway-bridge:3
    ports:
      - 1700:1700/udp
    volumes:
      - ./configuration/chirpstack-gateway-bridge:/etc/chirpstack-gateway-bridge
    depends_on: 
      - mosquitto

  postgresql:
    image: postgres:9.6-alpine

 environment:
      - POSTGRES_PASSWORD=root
    volumes:
      - ./configuration/postgresql/initdb:/docker-entrypoint-initdb.d
      - postgresqldata:/var/lib/postgresql/data

  redis:
    image: redis:5-alpine
    volumes:
      - redisdata:/data

  mosquitto:
    image: eclipse-mosquitto:2
    ports:
      - 1883:1883
    volumes: 
      - ./configuration/eclipse-mosquitto/mosquitto.conf:/mosquitto/config/mosquitto.conf

volumes:
  postgresqldata:
  redisdata:

Since your docker-compose.yml file looks like the example, have you tried doing what the Readme said:

When adding the Network Server in the ChirpStack Application Server web-interface (see Network Servers), you must enter chirpstack-network-server:8000 as the Network Server hostname:IP.

If you changed the port number, then you should enter the new port number instead of 8000.

Thanks so much! It works now.
