How to kill process on port on Windows when the port cannot be opened?

I'm on a Windows machine. Typically, when I need to kill a process on a port I do the following:

netstat -ano | findstr : <PORT>

After that command, the Process Identifier (PID) should appear and using that PID, I would do:

taskkill /PID <PID> /F

Then there's a response that the process has been terminated.

My issue now is that I'd like to kill the process on port 27017. So that I can use that port for a connection to Mongo. When I run: taskkill /PID 27017 /F I get the response FINDSTR: Cannot open 27017. Is there a way around this so that I can kill the task on that port. I've tried to restart as well, but that's not really doing me any good.

Any help would be appreciate and thanks in advance!
