Grafana TeslaMate Datasource issue

[stefanstranger]

I'm trying to configure the Grafana TeslaMate Dashboards, but when creating the PostgreSQL data source I'm getting the following error:

Metric request error.

What did I miss following the documentation here: https://docs.teslamate.org/docs/installation/debian#import-grafana-dashboards
