Since upgrading to Grafana 10.3 and Prometheus Alertmanager 0.27.x I’m getting this deprecation error message from alertmanager:

Failed to send test alert.: failed to send alert to Alertmanager: failed to send HTTP request - status code 410

Alertmanager tells me:  
level=warn msg=“HTTP request failed” url=[http://prometheus-kube-prometheus-alertmanager:9093/api/v1/alerts](http://prometheus-kube-prometheus-alertmanager:9093/api/v1/alerts) statusCode=“410 Gone” Body=“{"status":"deprecated","error":"The Alertmanager v1 API was deprecated in version 0.16.0 and is removed as of version 0.28.0 - please use the equivalent route in the v2 API"}”

So how do I make Grafana to use the v2 REST API of alertmanager? There is not config option to choose the version.

Sidenote: I do provision my alerting files. So my contactpoint.yaml looks like this:

apiVersion: 1  
contactPoints:

- name: Prometheus-Alertmanager  
orgId: 1  
receivers:
  - disableResolveMessage: true  
settings:  
url: [http://prometheus-kube-prometheus-alertmanager:9093](http://prometheus-kube-prometheus-alertmanager:9093)  
type: prometheus-alertmanager  
uid: alertmanager\_f0111d43

Hi! You need to update to Grafana 10.4 [grafana/CHANGELOG.md at main · grafana/grafana · GitHub](https://github.com/grafana/grafana/blob/main/CHANGELOG.md#1040-2024-03-06).
