When the CodeDeploy starts, it will be in process for 2-3 mins and fail in the fist step. with this error

this is the error description

CodeDeploy service is running fine and all the other setup looks good. Also not seeing any logs in CodeDeploy logs in EC2. please help out on identifying the issue.
