When launching the node (slave) I get the "Failed to connect error"
The node is configured to run the slave as a windows service.
There are total 3 nodes connected. All of them configured similarly. Just few weeks back the two of the nodes stopped launching. Happened after a windows patching from the IT department.
Is there anyway to figure out if there is any firewall or port issue?

I set my master URL to : http://[master_ip]:8080
I configured the windows slave machine as follows:
slave_config
Now I'm trying to launch the slave using the agent.jar by running the command:
java -jar agent.jar -jnlpUrl http://[master_ip]:8080/computer/slave_node/slave-agent.jnlp -workDir "C:\Jenkins"
and it can't connect for some reason:

Are you able to access the Jenkins master form the slave, there could be some connectivity issue, if there is no connectivity issue, try launching the windows slave from the browser
I have small Jenkins Environment of 2 windows servers ( Master and Slave ) .
I want to configure the Slave as a windows service .
while the "java -jar agent.jar -workDir "C:\JENKINS"" command working and getting the Slave running.The Launch agent from browser getting started and looping from connected to Terminated over and over again .
on the jenkins i see the errors :
Ping response time is too long or timed out.
Connection was broken

See if this is related to issue JENKINS-13696:
If I understand this issue correctly, I am having the same problem.
It appears that the plugin is trying to connect to FitNesse on the master (the FitNesse server is started correctly on the slave).
As a work around, I need to start the FitNesse server manually on the slave machine, and specify the option "Fitnesse instance is already running".
My error is
Connnecting to http://localhost:8085/RiskManagement.SomeSuitePage.AnotherSuitePage?suite&format=xml&includehtml
java.net.ConnectException: Connection refused: connect
The OP ramesh sriram mentions in the comments the cause of the error:
The port is closed/down.
I have the Jenkins master running on SUSE linux. I want to connect a Windows 8.1 system as a slave using JNLP. I followed the Jenkins CLI Connection mechanism guide and changed the Jenkins global security configuration.
Under TCP-Port for JNLP-Slave, I selected Static and entered the port as 49187. When the launch the JNLP connection on Slave system, after a while I get the "Read Timeout" error.
Could someone suggest what I am doing wrong?

I've installed jenkins on suse 12.1 and changed the port in the config to 8081
/etc/sysconfig/jenkins
JENKINS_PORT="8081"
The webinterface works without any problem on this port, but when I want to start the client with JNLP he gives me the standardport:
javaws http://192.168.1.137:8080/computer/192.168.1.190/slave-agent.jnlp
Now I tried to run it with the right port:
javaws http://192.168.1.137:8081/computer/192.168.1.190/slave-agent.jnlp
But after a short time I get an error:

He tries the wrong port. How can I change the port correctly?
Have you updated the URL via the configuration option under Manage Jenkins → Configure System → Jenkins URL?
