HTTP ERROR 404 Not Found

i have installed the jenkins and the service file also running but when i run http://localhost:8080 it shows an error HTTP ERROR 404 Not Found

Jenkins should run at http://localhost:8080/ and not http://localhost:8080/jenkins

i have tried with above mentioned url it shows error.

Just to be sure: When you use “localhost”, is your browser running on the same machine, as your jenkins is running on ?
I would use http://your_jenkins_hostname:8080
Replace “your_jenkins_hostname” by whatever the correct hostname for your jenkins server is.
