Hi,
I am using NetBeans 8.1 with Windows 10 64 bit. Few days ago I was able to ran Xdebug with Netbeans Connector normally, nothing changes in system, except some Windows automatic updates patches. 1-2 day recently, when I run debug project(Ctrl + F5) it's shows error below:


~~~~~~~~~~~~~~
"Xdebug - Internal Websocket server failed to start and communication with the external Chrome browser will not work. Check the IDE log for more information. This is likely caused by multiple instances of NetBeans running at the same time or some other application using port 8008"

I have tried run netbeans as administrator, tried to find out what process uses port 8008 but found nothing :

netstat -a -n | find "8008"

Reinstall netbeans connector, google chrome did not help either.

Please advise. Attached IDE log

Thank you very much in advanced

> Error exception in IDE log below:

This exception has nothing to do with Xdebug (or PHP support in NetBeans).

I do not know Windows so cannot help with this particular command but if it used to work and now you cannot connect to the port (the exception clearly says [1]), it seems to me to be a problem with your environment.

Anyway, it is unclear to me what are you doing exactly so please, reopen this issue and provide _exact_ steps to reproduce (and ideally also a sample project).

Thanks.
