Hi Pragathi,
Either you can restart your system, as Bharath suggested,
or you can open your task manager ( Ctrl +Shift+ Esc), find the OpenJDK and end this process, you can refer to the image below:
Once this process is done, try to start your Mendix server, it will start running,
Also, if there's another application running on the same server, then you need to change the server of this application,
From App(Module)> Settings> configuration
There, you will the option to change the server,
Let me know, if you have any issues,
Hope it helps!
Hi Pragathi,
Restart your machine or kill the port using command prompt by doing the following,
netstat -ano | findstr :<PORT>
taskkill /PID <PID> /F
