Troubleshooting PostgreSQL Database Connection Issues

Encountering issues while connecting to your PostgreSQL database can be frustrating, but we're here to assist! Below is a detailed guide to help you navigate through common error messages, understand their possible causes, and take actionable steps to resolve them.

1. Network Connection Refused

  • Error Message: "Please make sure that your database is running and you have whitelisted our IP address 34.100.193.122"

  • Action Steps:

    • Check Database Server: Ensure that your PostgreSQL server is running.

    • IP Whitelisting: Navigate to your PostgreSQL settings and ensure that the IP address 34.100.193.122 is whitelisted. This might involve modifying the pg_hba.conf file or adjusting firewall settings.

2. Network Connection Not Found

  • Error Message: "Please make sure that your database URL is correct"

  • Action Steps:

    • Verify Database URL: Ensure that the database URL in your connection settings is spelled correctly.

3. Incorrect Database Credentials

  • Error Message: "Incorrect database credentials. Please verify the username and password."

  • Action Steps:

    • Check Credentials: Confirm that the username and password in your connection settings match the credentials in your PostgreSQL server.

    • Reset Password: If needed, reset the password for the user in PostgreSQL and update it in your connection settings.

4. Database Does Not Exist

  • Error Message: "Database does not exist. Please verify the database name."

  • Action Steps:

    • Verify Database Name: Ensure that the database name in your connection settings matches an actual database in your PostgreSQL server.

5. Connection Attempt Timed Out

  • Error Message: "Connection attempt timed out. Please try again later."

  • Action Steps:

    • Server Status: Check if the PostgreSQL server is operational and not experiencing downtime.

    • IP Whitelisting: Navigate to your PostgreSQL settings and ensure that the IP address 34.100.193.122 is whitelisted. This might involve modifying the pg_hba.conf file or adjusting firewall settings.

6. Connection Timeout Exceeded

  • Error Message: "Connection timeout exceeded. Please verify the host and port details."

  • Action Steps:

    • Verify Host and Port: Confirm that the host and port in your connection settings are accurate and that the PostgreSQL server is listening on that host and port.

    • Firewall Settings: Ensure that any firewalls are not blocking the specified port.

    • IP Whitelisting: Navigate to your PostgreSQL settings and ensure that the IP address 34.100.193.122 is whitelisted. This might involve modifying the pg_hba.conf file or adjusting firewall settings.

7. Maximum Connection Limit Reached

  • Error Message: "Maximum connection limit reached. Please try again later."

  • Action Steps:

    • Close Unused Connections: Identify and close any unused or stale connections to the PostgreSQL server.

    • Increase Max Connections: Adjust the max_connections setting in the postgresql.conf file to allow for more concurrent connections, ensuring your server has sufficient resources to handle them.

8. IP Not Whitelisted

  • Error Message: "Unable to connect to the database. Please make sure that you have whitelisted our IP address 34.100.193.122"

  • Action Steps:
