• I observed the same error after our jenkins master was updated. It is likely due to incompatibility between Java 7 (v80) and latest Java 8.
• Check the java version being used by your master, and the java version of your slave.

• In my case, I am running swarm-client-2.0-jar-with-dependencies.jar on a linux host, and it was using Java 7.

  java version "1.7.0_80" Java(TM) SE Runtime Environment (build 1.7.0_80-b15) Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)

• Our jenkins master was upgraded and is now running Java 8

  java version "1.8.0_121" Java(TM) SE Runtime Environment (build 1.8.0_121-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

• When the java on the slave was updated to Java 8, the connection issues disappeared.
