Facing connection issues between DataSpell and a PostgreSQL database.

I'm encountering a puzzling challenge while trying to establish a connection between DataSpell and a PostgreSQL database. Despite following the standard procedures for setup, I keep running into an error that's hindering my progress.

Has anyone else faced similar connection issues with DataSpell and PostgreSQL? Could there be specific settings or configurations within DataSpell that I might have overlooked, leading to this problem? Additionally, are there any known bugs or limitations in DataSpell that could be causing these connection hurdles?

Moreover, I'm curious if there's a way to enable more detailed logging or diagnostic information in DataSpell to assist in troubleshooting this issue further.

I'd greatly appreciate any insights or suggestions from the community to help resolve this connection puzzle. Thank you all in advance for your assistance and expertise!

Hello,
Could be related to this problem: https://youtrack.jetbrains.com/issue/DBE-20539/new-version-almost-can-not-connect-to-Postgresql-server-14.11-which-previous-works-fine.
Please check the workaround from the last comment, and if it doesn't help, please upload DataSpell logs (Help | Collect Logs and Diagnostic Data) to our file hosting and tell us the upload ID: https://uploads.services.jetbrains.com/

Here are some common troubleshooting steps to help you resolve connection issues between DataSpell and a PostgreSQL database:

1. Check Database Connection Settings

  • Host: Make sure the hostname or IP address of the PostgreSQL server is correct.
  • Port: PostgreSQL typically runs on port 5432. Ensure this is specified correctly unless you are using a custom port.
  • Database Name: Verify that the database name you are trying to connect to is correct.
  • Username and Password: Double-check your credentials to ensure they are correct.

2. Check PostgreSQL Configuration

  • pg_hba.conf: Check the pg_hba.conf file on your PostgreSQL server to ensure it allows connections from the client’s IP address or host.

    • For example, adding the following line allows all IPs to connect (replace 0.0.0.0/0 with a more secure IP range if needed):

      bash

      Copy code

      host all all 0.0.0.0/0 md5

  • postgresql.conf: Ensure the PostgreSQL server is set to accept external connections by modifying the listen_addresses in postgresql.conf to '*':

    bash

    Copy code

    listen_addresses = '*'

3. Firewall and Network Configuration

  • Ensure there are no firewall rules on the PostgreSQL server that are blocking traffic on port 5432.
  • If you're on a cloud service (e.g., AWS, Azure), make sure security groups or network rules allow traffic to and from the PostgreSQL server. Click here for more.
