I have a strange setup on my new workplace and it works like this: if I have PhpStorm running and have "Start Listening for PHP Debug Connections" on, then my local PHP application works fine. As soon as I close PhpStorm completely (and consequently stop listening to PHP debug connections), then my webpage is not loading (nginx times out after a minute).
Here is my xdebug.ini config:
xdebug.mode=debug
xdebug.start_with_request=no
xdebug.discover_client_host=no
xdebug.client_host=127.0.0.1
xdebug.log_level=0
;xdebug.log=/var/log/xdebug.log
Here is the output of php -i | grep -i xdebug:

Interestingly, I even tried to completely uninstall Xdebug, but I was still having the same problem (I'm not sure if I did it correctly though).
Is there anyway that I prevent Xdebug to make connection? (and have it enable when I actually need to debug only)
I'm using PHP 7.4.25, Xdebug v3.1.1, and running it under WSL on Windows (Ubuntu 20.04). I'm also running everything behind nginx v1.21.4.
Update 1: As @LazyOne asked, here is my xdebug_info() output:

Here is the output of /etc/php/7.4/fpm/conf.d/xdebug.ini:

CodePudding user response：
Is there anyway that I prevent xdebug to listening?
No, because it is not Xdebug that is listening. It is Xdebug that makes a connection to PhpStorm, which can be listening for incoming debugging connections.
It is possible that for some reason, Xdebug still attempts to make a connection to the IDE, even if it is not listening. There is normally a 200ms timeout on the Xdebug side when connecting, but I have seen some network setups thwarting that.
In order to find out what, and if, Xdebug is still doing something, make a log file, by changing your xdebug.ini to include the following, and then restart Apache:
xdebug.log_level=10
xdebug.log=/var/log/xdebug.log
The log file will show you whether Xdebug is still attempting to connect in great detail (because you set xdebug.log_level to 10).
