This may be happening because some other application is trying to send something on the port of your application (8080). If you are using windows run the following command on the terminal to list the applications using the port netstat -a -n -o | findstr <porta> (Change to the port you want to locate) then run Taskkill /PID <pid> /F (Change the by the PID number found in the netstat command listing).
