CREATE_FAILED error in CloudFormation stack
If you encounter a CREATE_FAILED error when you launch the Quick Start, it is recommended that you relaunch the template with Rollback on failure set to Disabled. (This setting is under Advanced options in the AWS CloudFormation console, Configuring option settings page.) With this setting, the stack’s state is retained and the instance is left running, so you can troubleshoot the issue.
When you set Rollback on failure to Disabled, you continue to incur AWS charges for this stack. Please make sure to delete the stack when you finish troubleshooting.
For additional information, see Troubleshooting AWS CloudFormation on the AWS website.
The deployment will also fail if you select an instance type that is not supported in the region that was selected. Your desired instance type is available in your region if it is listed on the Instance types page for your region.
The election of the primary FortiGate was not successful
If the election of the primary FortiGate is not successful, reset the elected primary FortiGate. If the reset does not solve the problem, please contact support.
How to reset the elected primary FortiGate
To reset the elected primary FortiGate, navigate to the DynamoDB table <ResourceTagPrefix>-FortiGatePrimaryElection. Click the Items tab and delete the only item in the table.
A new primary FortiGate will be elected and a new record will be created as a result.
For details on locating the DynamoDB table <ResourceTagPrefix>-FortiGatePrimaryElection, refer to the section Locating deployed resources.
