PostgreSQL Connection Error

Hi all

I am trying to display a timeseries or a plain table from a postgresql table.
Unfortunately I get connectionerrors from the grafana server to the client. net::ERR_CONNECTION_RESET

polyfill.js:3 POST http://localhost:3000/api/tsdb/query net::ERR_CONNECTION_REFUSED

  1. queries: Array(1)
    0:
    refId: “A”
    intervalMs: 60000
    maxDataPoints: 1416
    datasourceId: 1
    rawSql: “SELECT * from data.some_table”
    format: “table”

tti-polyfill.js:3 GET http://localhost:3000/api/annotations?dashboardId=1&from=1580302666255&to=1580389066255 net::ERR_CONNECTION_REFUSED

When I save my datasource everything seems to be fine. There is no error displayed.

Does any have a clue what I did wrong or how I can troubleshoot it?

Do you have found any way to deal with this problem? I am also suffering with this now…

No unfortunately not …
But I haven’t done any further investigation.

For me it’s total unclear, why it is not working. Because on my localhost DB I don’t have any special settings or restrictions. So I thought it should work out of the box.
