I Downloaded the war file from the Jenkins site and started on custom port. "INFO: Jenkins is fully up and running" is shown after running several instructions. But when I tried it on a browser with "http://localhost:port" it is not connecting. It's throwing a message: "the webpage is not available"

My system contain java version 1.6 and the downloaded version of Jenkins is 1.5.

Please let me know how to resolve this issue.

  • I think Jenkins is default started on :8080 and not on :port – Niels van Reijmersdal Jun 26 '15 at 12:02
  • Can you provide some more information; are you using windows, linux or a mac. Did you start Jenkins using the command line or is it installed as a service. It would also help if you included the log file in your question. – GrahamA Jun 26 '15 at 19:43
  • Am having similar problem on mac and I have tried localhost:8080/jenkins and it returns 404 code. Can someone assist me with this issue pls – user31673 Mar 22 '18 at 16:28
  • I am also facing the same issue .. I have docker in my system and also installed Jenkins through official site.It was successfully installed however, localhost is not opening in browser I am done all this on Mac. – Rishabh Patel Jun 12 '19 at 14:45

  • Yes it works, I am running the jenkins on windows machine – Bunny Jun 30 '15 at 5:03

Running jenkins in Docker and unable to access jenkin's landing page via http://localhost:8080?

Check the IP address that Docker configured to use for the default machine. Hence, jenkins is accessible via http://configured-ip:8080
