When configuring, I encountered the following problems, record them.
1. Configure according to the tutorial, the node server (such as the test server you want to deploy) always displays a red X and cannot be connected, indicating that the connection time out.
Possible reasons: Master server is unix/linux, Slave is windows, jenkins has bugs:

Solution: upgrade jenkins
