I attached the verbose logs.   When I do a curl from the slave to the master I see 50000 is available. [ec2-user@ip-10-0-6-121 ~]$ curl 10.0.7.19:50000 Jenkins-Agent-Protocols: JNLP4-connect, Ping Jenkins-Version: 2.182 Jenkins-Session: 02bf8ba3 Client: 10.0.6.121 Server: 10.0.7.19 Any ideas would be appreciated, I am currently just downgrading Jenkins to previous versions to see if that will help.
