      Description

      Hello,

      I am currently running Jenkins 2.138.3 with plugin version 3.12, I am attempting to upgrade to Jenkins 2.182 and plugin 3.17.

       

      Looks like I am getting an error that it can't connect to port 50000 (the fixed agent port). 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
      Remoting-Minimum-Version: 3.4
      

      Any ideas would be appreciated, I am currently just downgrading Jenkins to previous versions to see if that will help.
