Cannot start Jenkins agent on AWS ECS - amazon-web-services

Question

I am deploying Jenkins slaves on ECS. I followed the following article and provisioned it with AWS CDK link. However, when I started the task definition for Jenkins agent, the status of task was stuck at PROVISIONING. I checked the CloudWatch logs and got the following error:

I tried with port 50000 and different OS and images but it keeps failing.
The security groups for Jenkins master and agent are set to allow all traffic.
