I'm running the official Alertmanager app (io.prometheus.alertmanager.cloudronapp) and I'd like an external Prometheus instance (not hosted on this Cloudron) to push alerts to it via POST /api/v2/alerts.

All requests to any path (including /api/v2/* and /metrics) get redirected to /login — confirmed this is the proxyAuth OIDC wall, not a credentials issue (tested with a generated Cloudron app password, Bearer token, and no auth at all: all get the same 302).

I found that the Prometheus app already solved exactly this: basicAuth was enabled so it can work with apps like Grafana (v1.4.1, May 2021).

Could the Alertmanager package get the same basicAuth: true treatment in its proxyAuth config? That would let external Prometheus instances authenticate and push alerts, the same way Grafana already talks to Prometheus.

Thanks!
