Grafana Telegram 警报问题无法发送警报通知

Question

我正在尝试在 Grafana 上设置电报通知，但收到此错误

测试无法发送通知。 这是我的 docker-compose.yml 文件

version: "3.7"

services:
  loki:
    image: grafana/loki:1.4.1
    ports:
      - "3100:3100"
    command: -config.file=/etc/loki/local-config.yaml

  promtail:
    image: grafana/promtail:1.4.1
    volumes:
      - /var/lib/docker/containers:/var/lib/docker/containers
      - /var/www/nt_devops/monitoring/docker-config.yml:/etc/promtail/docker-config.yml
    command: -config.file=/etc/promtail/docker-config.yml

  grafana:
    image: grafana/grafana:master
    ports:
      - "9095:3000"
    volumes:
      - grafana_data:/var/lib/grafana
      - grafana:/etc/grafana
   

volumes:
  grafana_data:
  grafana:

这是我的 grafana 容器日志

我正在使用主机网络，没有任何其他网络。我认为这是网络问题

这是浏览器控制台错误
