Thanks so much Terry for your help, indeed I realized that in the command line:
java -jar slave.jar -jnlpUrl https://<master_node>:443/computer/<slave_windows_hostname>/slave-agent.jnlp -secret <long_hex_string> the <master_node> string was missing the domain, so I changed this information in: Jenkins-> Configuration->Jenkins URL and I added the domain name also to the master hostname input. I solved the problem SSLHandshakeException. However, there is still a problem while trying to launch the application from the web. When I try to launch it still I get an exception: java.lang.NullPointerException at com.sun.deploy.security.DeployManifestChecker.verify(Unknown Source) [.........] On the other hand when execurting the command manually (java -jar slave.jar -jnplUrl https:.....) I get the message: Failing to obtain https://<master_node>:443/computer/<slave_windows_hostname>/slave-agent.jnlp?encrypt=true java.io.IOException: https://<master_node>:443/computer/<slave_windows_hostname>/slave-agent.jnlp?encrypt=true doesn't look like a JNPL file; content type was text/html; charset=utf-8 Would you have any hint concerning this issue?
