Jenkins slave goes offline with message “ERROR: Connection terminated / Connection aborted”

Question

One of our Jenkins slaves went offline with the following message:

ERROR: Connection terminated
java.io.IOException: Connection aborted: org.jenkinsci.remoting.nio.NioChannelHub$MonoNioTransport@5fe56036[name=node-helloworld]

We already restarted the slave and the Jenkins master. Unfortunately nothing helped. Log analysis neither.

Both, master and slave run on Windows Server 2008.

Do you know what could have caused the problem and how it can be solved?

The slave is on and running. But Jenkins master cannot connect it. Or vice versa. — andreasgk

What version of Jenkins are you using? What is it the specs of the agent? What Java version do you have in the agent? — Daniel Hernández

I had the same issue with Jenkins 2.6 on linux. Fixed it by upgrading the java version on the slave from Java 7 to Java 8.
