Hi,

I have started a 2.178 instance from scratch, installing suggested plugins, and the agent port configuration is behind Markup Formatter as expected.

So on your picture, it shows The TCP agent protocols- nothing about JNLP or JAVA - nor is this in the documentation anywhere. The documentation does not explain what port should be set or how to get JNLP working for a windows agent- they all just say use "JNLP" and "Java web start" which don't exist in 2.18.0 by default. There are lots of documentation pages that provide lots of different static port options for JNLP, none of which make the start agent with java web start option work in the agent configuration.. and this is after checking all the documentation for the java version 8, etc down in the details of the comments. It seems from the release notes that it was very visible and straightforward in 2.16 but was hidden? So how do you get to see JNLP protocols in that picture you posted?

Since you're trying to connect agents and the agents communicate over TCP, use the section labeled "Agents" and the line that says "TCP port for inbound agents".  Insert a valid port value for the TCP port for inbound agents.  Apply that change.

Then add an agent and choose "Launch agent by connecting it to the master".

The phrasing has been improved significantly in the user interface by removing the references to "JNLP".  The key difference between the agent protocols is not the underlying transport, but rather which end initiates the connection.  The agent launch method that was formerly called "JNLP" is a launch method that initiates the agent connection from the agent to the master.  The launch method called "ssh" initiates the connection from the master to the agent.
