I attached the verbose logs.   When I do a curl from the slave to the master I see 50000 is available.

Re: Swarm cannot connect to Jenkins Master provided port:50000 is not reachable Hey Joey Khashab, does this failure happen consistently or is it transient?

Re: Swarm cannot connect to Jenkins Master provided port:50000 is not reachable Basil Crow thanks for your reply, after trying several things, I realized I was passing in `-Dhudson.TcpSlaveAgentListener.hostName=master_ip` into my Jenkins as part of my Chef provisioning for Jenkins master, after putting in the correct IP address for master it seems to be working. Cancelling this issue.
