Metric request error with PostgreSQL

#1

Hello everybody
I constantly get the error message “Metric request error” and can not connect to the PostgresSQL database. Can anybody help me further?

#2

Using 6.1.6 Grafana + PostGre.

I noticed, that if you leave “Host” parameter as default (untouched) -> even the default is correct, it will cry this “Metric error”. If you type something in or touch, so it comes “white” -> No Metric error.

Anyone else can reproduce this?
