Failed To Run Sql Query Connection Terminated Due To Connection Timeout

This error typically happens when the database is overloaded and causing an outage. As the database does not respond in a timely manner there can be a variety of symptoms such as tables not loading, error messages related to retrieving data and the dashboard seems to be unresponsive.

• Check your database health in Database reports.
• If needed, increase resources in Compute and Disk.
• Alternatively, you can restart the database in Project Settings but this may be only a temporary fix if the project is undersized / unoptimized.

Review the appropriate guides based on your scenario:

• High CPU usage
• High RAM usage
• High Swap usage
• High Disk I/O
• Query optimization

You can also set up alerts using a Prometheus endpoint / Grafana charts to monitor vital resources.
