Xdebug Could not connect to debugging client. Tried: localhost:9000

Question

I used before Xdebug v2, but after last update I faced with Xdebug v3.0.0, I replaced all what needed by the update user guide

I'm using Docker.

my debug conf

#xdebug.remote_enable=true xdebug.mode=debug  #xdebug.remote_port=9000 xdebug.client_port=9000  xdebug.remote_host=172.17.0.1  xdebug.remote_handler=dbgp  #xdebug.remote_autostart=1 xdebug.start_with_request=yes  #xdebug.remote_connect_back=0 xdebug.discover_client_host=0  xdebug.idekey=PHPSTORM xdebug.show_error_trace = 1 xdebug.max_nesting_level=250 xdebug.var_display_max_depth=10 #xdebug.remote_mode=req  xdebug.remote_log=/var/log/r_xdebug.log xdebug.log=/var/log/xdebug.log 

and what I get in log when try to execute any PHP script :

tail -f /var/log/xdebug.log [888] Log opened at 2020-11-29 10:39:51.670762 [888] [Step Debug] INFO: Connecting to configured address/port: localhost:9000. [888] [Step Debug] WARN: Creating socket for 'localhost:9000', poll success, but error: Operation now in progress (29). [888] [Step Debug] WARN: Creating socket for 'localhost:9000', connect: Cannot assign requested address. [888] [Step Debug] ERR: Could not connect to debugging client. Tried: localhost:9000 (through xdebug.client_host/xdebug.client_port) :-( [888] Log closed at 2020-11-29 10:39:57.515970 

When I try to execute the URL in a browser PhpStorm does not start debugger, but I checked

lsof -i :9000 | grep LISTEN 

listen port appeared when I click listening in PhpStorm. My conf was sync File | Settings | Languages & Frameworks | PHP | Debug -> Debug port 9000

What's wrong with my Xdebug config and what I need to do?
