-
I am using the online hosting @ https://hgobs.grafana.net/.
-
I am creating a new datasource to connect to RDS PostGres Proxy which is available in VPC
-
Postgres version that we are using is 17, I have select “15” from option drop down as it’s the closest that is available
-
I have created and successfully connected a “Private data source connect”/
-
Now I am configuring the datasource, and getting following error when I lock button “Save & test”. When I try with wrong port i.e. 123, it fails with a different error. as you can see in agent logs
There was an error when testing this data source, please check PDC agent logs.
driver: bad connection
