Prometheus Alert Manager error "component=cluster err="couldn't deduce an advertise address" and "unable to initialize gossip mesh"

Question

I'm new to Prometheus and I'm trying to install Alert Manager module.

Using Prometheus 2.19.2, Node exporter 1.0.1 and Alert Manager 0.21.0 on Debian 10.

Configuration files:

Prometheus:

alerting:
  alertmanagers:
  - static_configs:
    - targets:
      - localhost:9093"

Alert Manager:

global:
  smtp_smarthost: 'localhost:25'
  smtp_from: '[email protected]'
  smtp_auth_username: ''
  smtp_auth_password: ''
  smtp_require_tls: false

templates:
- '/etc/alertmanager/template/*.tmpl'

route:
  repeat_interval: 1h
  receiver: operations-team

receivers:
- name: 'operations-team'
  email_configs:
  - to: '[email protected]'

The issue is about Alert Manager service that throws an error on starting:

Jul  9 19:08:11 mail alertmanager[851]: level=warn ts=2020-07-09T17:08:11.887Z caller=cluster.go:154 component=cluster err="couldn't deduce an advertise address: no private IP found, explicit advertise addr not provided"

Jul  9 19:08:11 mail alertmanager[851]: level=error ts=2020-07-09T17:08:11.901Z caller=main.go:241 msg="unable to initialize gossip mesh" err="create memberlist: Failed to get final advertise address: No private IP address found, and explicit IP not provided"

I've been looking in Internet but haven't found a solution yet...

Any ideas?

Thanks

you should add arg "--cluster.advertise-address=0.0.0.0:9093" when startup
