      Description

      I have updated Jenkins to the latest version (Jenkins ver. 2.164.1) and Selenium Grid version is: 3.12.0. Java varsion on master (where run the hub) is: openjdk version "1.8.0_191", on the slave is: java version "1.8.0_191" and SSH Slave plugin version 1.11. When the nod is trying to connect to slave is throw this error:

          it does not work on ssh-slaves 1.11 and 1.29 I guess it is not a bug, it looks like more a configuration issue, to as question about how to configure something please use the user groups see [How to report an issue](https://wiki.jenkins.io/display/JENKINS/How+to+report+an+issue)
