PHP Xdebug Doesn't work in VSCode - Windows + IIS - php

Question

I have a problem with PHP Xdebug on VSCode.
My environment is Windows Server 2012 R2, I have installed VSCode and running IIS server with PHP 7.4, with Xdebug 3
When I open script with xdebug_info() from Firefox, then Xdebug log produces output. But when I hit F5 in VSCode there's no output (seems like extension doesn't connect with Xdebug at all).
VSCode config (it's default):
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.

"version": "0.2.0",
"configurations": [
{
"name": "Listen for Xdebug",
"type": "php",
"request": "launch",
"port": 9003,
"log": true,
},
{
"name": "Launch currently open script",
"type": "php",
"request": "launch",
"program": "${file}",
"cwd": "${fileDirname}",
"port": 9003,
}
]
}
php.ini:
[XDebug]
zend_extension = "c:\Program Files\PHP\v7.4\ext\php_xdebug-3.0.4-7.4-vc15-nts-x86_64.dll"
xdebug.mode = debug
xdebug.start_with_request = yes
xdebug.client_host=::1
xdebug.log = "c:\inetpub\xdebug_log.log"
VSCode debug output:
<- launchResponse
Response {
seq: 0,
type: 'response',
request_seq: 2,
command: 'launch',
success: true
}
But I don't see any variable's values at all. Breakpoints doesn't work too.
When I try to call something in debug console, the output is:
Cannot evaluate code without a connection
Which could be inferred from no-log entries produced by VSCode requests. I spent about 4 hours about googling this problem, but couldn't find solution.
