AWSEBInstanceLaunchWaitCondition: WaitCondition timed out

Hi,

I'm in a trouble on Beanstalk with Cloudformation.

I have a Cloudformation template, which creates AWS::ElasticBeanstalk::ApplicationVersion, ConfigurationTemplate and Environment, it's always completed fine.
Then, executing the template mentioned above seems to try stacking another template automatically, whose name is "awseb-e-...-stack", which ends in failure.
Events of "awseb-e-...-stack" shows "CREATE_FAILED" because "WaitCondition timed out. Received 0 conditions when expecting 1" for "AWSEBInstanceLaunchWaitCondition".
I looked into the template for the stack and come to see "AWSEBInstanceLaunchWaitCondition" was waiting for "AWSEBAutoScalingGroup" however, I have no idea at all to solve the problem.

Can anyone kindly suggest any clue, or share experiences/resolution on similar issues? Any help would be greatly appreciated.

Thank you.
