Hello,

I’m trying to update the rack with spot instances, but always I receive the same error:

11:23:19 UTC-0200 UPDATE\_FAILED AWS::AutoScaling::AutoScalingGroup SpotInstances Received 0 SUCCESS signal(s) out of 4. Unable to satisfy 100% MinSuccessfulInstancesPercent requirement  
11:23:17 UTC-0200 UPDATE\_IN\_PROGRESS AWS::AutoScaling::AutoScalingGroup SpotInstances Failed to receive 1 resource signal(s) for the current batch. Each resource signal timeout is counted as a FAILURE.
