Hi, I'm trying to configure inbound agent (slave). For this purpose I've defined in Jenkin's Global security setting
TCP port for inbound agents: Fixed: 8081, and created a new node. *The node settings page suggests the following command to be run on the agent:* java -jar agent.jar <https://ci.adam-cogtec.com:8080/jnlpJars/agent.jar> -jnlpUrl http://ip:8080/computer/NODE/slave-agent.jnlp -secret SECRET -workDir "/home/pi/jenkins" This is strange, as I configured the TCP Port for inbound connections to be 8081, not 8080. Moreover, the server itself is secuted with TLS, however jenkins suggests to use HTTP. *Running the command produces the following error:* Failed to obtain http://ip:8080/computer/NODE/slave-agent.jnlp?encrypt=true java.net.SocketException: Unexpected end of file from server at sun.net.www.http.HttpClient.parseHTTPHeader(HttpClient.java:851) at sun.net.www.http.HttpClient.parseHTTP(HttpClient.java:678) at sun.net.www.http.HttpClient.parseHTTPHeader(HttpClient.java:848) at sun.net.www.http.HttpClient.parseHTTP(HttpClient.java:678) at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1593) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1498) at java.net.HttpURLConnection.getResponseCode(HttpURLConnection.java:480) at hudson.remoting.Launcher.parseJnlpArguments(Launcher.java:517) at hudson.remoting.Launcher.run(Launcher.java:347) at hudson.remoting.Launcher.main(Launcher.java:298) Waiting 10 seconds before retry *Trying to change port to 8081 produces:* Failed to obtain http://ip:8081/computer/NODE/slave-agent.jnlp?encrypt=true java.io.IOException: Failed to load http://ci.adam-cogtec.com:8081/computer/VitaliysAutoPi/slave-agent.jnlp?encrypt=true: 404 Not Found at hudson.remoting.Launcher.parseJnlpArguments(Launcher.java:519) at hudson.remoting.Launcher.run(Launcher.java:347) at hudson.remoting.Launcher.main(Launcher.java:298) Waiting 10 seconds before retry *Changing the URL to https & port 8081 hangs for a long time.* *Changing the URL to https & port 8080 produces the following error:* Oct 31, 2020 7:23:14 PM hudson.remoting.jnlp.Main$CuiListener error SEVERE: Handshake response not received. io.jenkins.remoting.shaded.javax.websocket.DeploymentException: Handshake response not received. at io.jenkins.remoting.shaded.org.glassfish.tyrus.client.ClientManager$3$1.run(ClientManager.java:694) at io.jenkins.remoting.shaded.org.glassfish.tyrus.client.ClientManager$3.run(ClientManager.java:712) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at io.jenkins.remoting.shaded.org.glassfish.tyrus.client.ClientManager$SameThreadExecutorService.execute(ClientManager.java:866) at java.util.concurrent.AbstractExecutorService.submit(AbstractExecutorService.java:112) at io.jenkins.remoting.shaded.org.glassfish.tyrus.client.ClientManager.connectToServer(ClientManager.java:511) at io.jenkins.remoting.shaded.org.glassfish.tyrus.client.ClientManager.connectToServer(ClientManager.java:355) at hudson.remoting.Engine.runWebSocket(Engine.java:628) at hudson.remoting.Engine.run(Engine.java:470) *So which URL should be the right URL, and how would you troubleshoot this issue?* Many Thanks!
