Tomcat Debug Error: Unable to open debugger port (127.0.0.1:63199): java.net.BindException "Address already in use: NET_Bind"

Question

I woke up for work and started receiving this error, but I can't find this specific error anywhere.

I tried using netstat -ano to find any instances running on the aformentioned port, and also the ports I run Tomcat on:

HTTP port: 8090 JMX port: 1099

But no processes are running on any of the three ports. Any ideas?

Have you checked the 63199 port? Try restarting the PC. Check also this thread for solutions. — Andrey

@Andrey I have looked for the port via netstat. I followed you link and took the TCPView software from the top of the list and none of the ports listed in my post appear on this list. — Jeremy Villa

I can't seem to find a stack trace of this exception in the Jetbrain Directory or the Intellij Directory. How can I find a more comprehensive read out of this issue? — Jeremy Villa

if you have installed any anti-virus, disable it and try once. -ibm.com/developerworks/community/forums/html/… — Ramesh Subramanian

This works for me. Just change the port number. E.g. to 59072.

Restart your Idea. It works for me.

Previously, I tried: net stop winnat. But not working. I got received the message:
"El servicio de Controlador de Windows NAT no se ha iniciado. Puede obtener más ayuda con el comando NET HELPMSG 3521."

Sorry for my English (fix me please)
