      After upgrading Jenkins to the latest version docker slaves from image jenkinsci/slave keep failing to connect. In job I see error:

      If I start docker slave from jenkinsci/slave (version 3.10) manually by command docker run --entrypoint java jenkinsci/slave -Djava.io.tmpdir=/home/jenkins/.tmp -jar /usr/share/jenkins/slave.jar I get:

      <===[JENKINS REMOTING CAPACITY]===>rO0ABXNyABpodWRzb24ucmVtb3RpbmcuQ2FwYWJpbGl0eQAAAAAAAAABAgABSgAEbWFza3hwAAAAAAAAAP4=Exception in thread "main" java.io.EOFException: unexpected stream termination

      As result I see a lot of failed containers:
