Alertmanager：Slack 通知 - x509：由未知机构签署的证书

如何解决Alertmanager：Slack 通知 - x509：由未知机构签署的证书

我正在尝试为通知配置 Prometheus alert-manager 和 slack。但它失败并出现以下错误。

alertmanager    | level=warn ts=2021-01-11T05:53:56.925Z caller=notify.go:674 component=dispatcher receiver=slack integration=slack[0] msg="Notify attempt Failed,will retry later" attempts=1 err="Post \"<redacted>\": x509: certificate signed by unkNown authority"
alertmanager    | level=error ts=2021-01-11T05:54:06.019Z caller=dispatch.go:309 component=dispatcher msg="Notify for alerts Failed" num_alerts=1 err="slack/slack[0]: notify retry canceled after 7 attempts: Post \"<redacted>\": x509: certificate signed by unkNown authority"

我的 alertmanager.yml 配置文件如下。

global:
  resolve_timeout: 5m

route:
  group_by: ['alertname']
  group_wait: 10s
  group_interval: 10s
  repeat_interval: 1h
  receiver: 'slack'
receivers:
- name: 'slack'
  slack_configs:
  - api_url: "Slack webhook api"
    channel: '#slack channel'
    send_resolved: true

在alertmanager中解决这个问题的方法是什么？
