Hi,When I run query on fleet UI,the fleet log show the error message below
```fleet_3         | 2021/09/01 07:08:44 http: TLS handshake error from 10.17.1.21:36762: remote error: tls: unknown certificate```

10.17.1.21 is the front nginx proxy to fleet

my docker-compose is as below
```services:
  fleet_proxy:
    image: ${DOCKER_REGISTRY}/nginx:1.18-alpine
    restart: always
    volumes:
      - $PWD/nginx/nginx.conf:/etc/nginx/nginx.conf
    ports:
      - 8412:8412```
and fleet service is scale to 4

nginx.conf is as below
```user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

stream {
    upstream FLEET {
        server fleet:8412;
    }

    server {
        listen 8412;
        proxy_pass FLEET;
    }
}```
