If you have a problem using the default port, try another port.

For example:

rails server -p 4000

Since you mention you are running Windows and using vagrant, I'll make the assumption that vagrant is running a POSIX based operating system such as Debian, CentOS, etc.

You should ssh into the vagrant machine and find the process of the WEBrick server that is running and terminate it. You may need to do sudo if the instance was started by a process or job having a different UID than your user.

To find a process id to kill you can use ps. However since you know the port that is being used, you could use fuser with the -k flag as well.

fuser -k 3000/tcp

or

sudo fuser -k 3000/tcp

or any of the following:

Rails server says port already used, how to kill that process?

If you require sudo and you are not in the sudoers file and cannot su to root (don't know the password) or access the user or group that started the process, contact whomever set you up with the vagrant instance and ask how you can have your credentials added to sudoers.

Make sure you have no other Rails servers running.

There is another process running on the same port.

If that's a webrick, Try killall -9 ruby and check again.

Right, I didn't notice that. Kill the process with process manager then.

To Ensure that no rails server is running now, you need to do something like this:

Go App root directory -> tmp -> pids and then delete server.pid

It will ensure that no process is runing for your server and then restart your server once again.

Or you can run your rails server by using another port if u need then run the bellow command in the terminal or command prompt:
```
                       rails server -p 5000
```

Or you may try this :

                      lsof -wni tcp:3000

And then kill the process, collect PID from the result of above command:

                           kill -9 PID
