I’m use Grafana version 9.3.2 on Linux Mint 20
During the connection with Postgres plugin (PSQL installed on the same machine, with user and password checked and correct) I got the error in the subject “An error occurred within the plugin”.
I couldn’t found any log error (I’ve get a look to PSQL log but there’s no error) and in /var/log/ on the docker container where run Grafana Loki also no problem of any type
