trying to set up ec2 instance with abctl and an external rds, but getting this error on the install:

ERROR   airbyte-bootloader: i.a.d.c.DatabaseAvailabilityCheck(lambda$isDatabaseConnected$1):78 - Failed to verify database connection.

Based on the error message you've provided, it appears you're encountering a database connection issue while trying to set up Airbyte with an external RDS instance. This is a common problem when configuring Airbyte with external databases. Let's break down the error and suggest some potential solutions: 1. Connection Timeout: The error indicates that the connection attempt to the database timed out after 30 seconds. This could be due to network issues or incorrect database configuration. 2. Unknown Host: The last line of the error message suggests that the hostname "database-host" cannot be resolved. This is likely the root cause of your connection problem. To resolve this issue, consider the following steps: 1. Verify Database Host: Ensure that the database host you've specified in your Airbyte configuration is correct. The error suggests you're using "database-host" as the hostname, which is likely a placeholder. Replace this with the actual endpoint of your RDS instance. 2. Check Network Configuration: Make sure that the EC2 instance where you're running Airbyte can reach the RDS instance. This might involve: - Configuring the RDS security group to allow inbound traffic from your EC2 instance. - Ensuring that the EC2 instance is in the same VPC as the RDS instance, or that proper VPC peering is set up if they're in different VPCs. 3. Verify Database Credentials: Double-check that the username, password, and database name in your Airbyte configuration are correct. 4. Check Database Availability: Ensure that your RDS instance is running and accessible. 5. Review Airbyte Configuration: Make sure you've properly configured Airbyte to use your external RDS instance. This typically involves setting the correct environment variables or updating the configuration files. If you continue to face issues after verifying these points, you might want to check the Airbyte logs for more detailed error messages. The error you're seeing is similar to those reported in other Airbyte connection issues, such as the one discussed in [this GitHub issue](https://github.com/airbytehq/airbyte/issues/45456). Remember to never expose sensitive information like database credentials in public forums. If you need further assistance, consider reaching out to Airbyte's community support channels with sanitized logs and configuration details.
