I've setup a Jenkins master in AWS ECS and running Amazon EC2 Container Service Plugin for Slave.

Current AMI im using is:* ami-275ffe31*

instance type: t2.medium

have added in* Jenkins Master > Managed Jenkins > Script Console *

Jenkins.instance.injector.getInstance(hudson.slaves.ChannelPinger.class).@pingIntervalSeconds = -1
Jenkins.instance.injector.getInstance(hudson.slaves.ChannelPinger.class).@pingTimeoutSeconds = -1

Also added in the Amazon EC2 Container Service Plugin
ECS task creation timeout to 90000

Added in JVM arguments in Slave

-Dhudson.remoting.Launcher.pingIntervalSec=-1

Somehow still getting Error below:
