- Test Connection Outside the Application: Sometimes, connection issues might be specific to your application. Test the connection independently using tools like Telnet or dedicated database client tools. For MySQL, you can use tools like MySQL Workbench or phpMyAdmin, while for PostgreSQL, options include pgAdmin and DBeaver; for Microsoft, SQL Server and SQL Server Management Studio (SSMS) are popular choices.
- Contact Hosting/Server Support: If all else fails, don't hesitate to seek assistance from your hosting provider or server administrators. They can provide valuable insights into server-side issues and may be able to resolve them swiftly.
By following these troubleshooting steps systematically, you can identify and resolve database connection issues effectively, ensuring that your database connections are stable and reliable for your applications.
