You can track down the process running on port 8080 and kill it.

For macOS or Linux:

sudo lsof -iTCP:8080 -sTCP:LISTEN

You should get an output something like:

COMMAND   PID USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME

yarn    12017 user   12u  IPv6 1876683      0t0  TCP *:8080 (LISTEN)

Now that you have the process ID(PID), you can kill the process. First try:

kill 12017(whatever the PID is)

If that does nothing, try:

kill -9 12017

For Windows:

netstat -ano | findstr :8080 (the port number)

This should give you the process to kill. You can then run:

taskkill /F /PID 12017(or whatever the process ID is)
