Can't connect to certain port - How to unblock port

I am running a Apache2 Webserver with PHP 7 and xdebug. I try to establish a connection between my IDE (Netbeans) and xdebug running on my webserver.

I read here that I have to check if I can connect to the client where the IDE runs

So I executed this command from my webserver, like recommended:

telnet 192.168.40.161 9000

Hint: 9000 is the port configured in php.ini for xdebug

Result:

Trying 192.168.40.161...
telnet: connect to address 192.168.40.161: Connection timed out

I configured the windows firewall like this:

Why does telnet fail to connect?

More Infos:

php.ini entry for xdebug:

[XDebug]
zend_extension = /usr/lib64/php7/extensions/xdebug.so
#zend_extension = /usr/lib64/php7/extensions/xdebug_2.6.so

xdebug.force_display_errors=on
xdebug.force_error_reporting=on
xdebug.remote_enable=on
xdebug.remote_handler=dbgp
xdebug.remote_host=localhost
#xdebug.remote_host=192.168.40.161

xdebug.remote_timeout=3000
xdebug.remote_port=9000
xdebug.remote_mode=req

If you completely disable the Windows firewall can you connect? – Zumo de Vidrio – 2019-07-31T11:41:44.677

@ZumodeVidrio, I can't completly disable it, because only the sysadmin has the right. But I disabled it for public and private. I can't disable it for domain. Makes no difference. – Black – 2019-07-31T12:59:33.760

Can you verify if your webserver is listening in port 9000? – Zumo de Vidrio – 2019-07-31T13:05:52.530

I executed netstat -a | grep 9000 but there is no result – Black – 2019-07-31T13:07:04.647

Then xdebug is not running properly, Is it running with another port or it isn't running at all? – Zumo de Vidrio – 2019-07-31T13:22:25.277

The port is 9000, it also creates a log entry in /var/log/xdebug/xdebug.log saying that the connection timed out after 3000 ms. – Black – 2019-07-31T13:36:16.140

Is there any process running about xdebug? (I don't know how it works) If so, can you find an associated port via netstat? – Zumo de Vidrio – 2019-07-31T13:38:04.167
