Delay on showing event or LoRaWAN frames

ChirpStack (v4)
1

In the Application Server version 3 the events were updated in real time, when I upgrade to version 4 (following this steps) the events load in batch every 30 seconds approximately (not even periodically). This is only on the frontend instance of chirpstack, because in the integration http endpoint data appears in real time as expected.

This is important to debugging visualization of the data on my endpoint, so, any advice of debugging is welcomed.

I also change from direct installation on server (using apt install) to docker version using the official image (docker hub: chirpstack/chirpstack) and manual.

I let some additional technical information:

  • AWS Lightsail, Virginia, Zone A (us-east-1a)
  • 2 GB ram, 2 GB RAM, 1 vCPU, 60 GB SSD
  • Ubuntu 18.04 LTS
  • URL {myserver}/#/tenants/{tenant-uuid}/applications/{app-uuid}/devices/{dev_eui}/events
  • Nginx reverse proxy version

Nginx Configuration for this server:

# Chirpstack
server {
    listen              443 ssl;
    server_name         [redacted];
    ssl_certificate     [redacted];
    ssl_certificate_key [redacted];

    location / {
        proxy_pass      http://127.0.0.1:8080;
    }
}

Thanks in advance,

I added the grpc to nginx and worked:

location ^~ /api { 
    grpc_pass grpc://localhost:8080; 
    }

Just in case someone else needed
