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](https://stackoverflow.com/questions/12737293/how-do-i-resolve-the-java-net-bindexception-address-already-in-use-jvm-bind) for solutions. — Andrey, Apr 21 '20 at 14:30
@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, Apr 21 '20 at 14:36
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, Apr 21 '20 at 14:45
if you have installed any anti-virus, disable it and try once. -https://www.ibm.com/developerworks/community/forums/html/threadTopic?id=77777777-0000-0000-0000-000014469562 — Ramesh Subramanian, Apr 23 '20 at 04:49

This works for me. Just change the port number. E.g. to 59072. – andy Nov 14 '22 at 08:54
