Xdebug configuration under X11 forwarding Follow
I have WSL2 + X11 forwarding via X410 enabled (offers WAY better DX than standard setup). The PHP runtime in Docker container(s). Although it all works very well, I'm not able to set-up the Xdebug 3 for the current situation. What's the officially suggested way?

There's no officially suggested way, unfortunately, there are way too many variables. In general, you need to find an IP/hostname that you can use to connect from the container to the Linux host.
I find it useful to create a listener on the host I want to connect to with
nc -l 9005and thentelnet hostname 9005from the container trying to find a hostname that works.Then, you'll just have to specify this hostname as
xdebug.client_host.Is it Docker Desktop with the WSL2 engine or you've installed Docker in the WSL directly, with `apt`?
Eugene Morozov thanks, great advice.
The docker backend is the WSL2 one. Nevertheless when I create the listener it occupies the given port on IPv4 and one can telnet from docker container with host.docker.internal which is perfectly fine. At the same time when I start the listener from PHPStorm, it occupies the port on IPv6. Is there a way to configure that?
does the trick
Yep, for some reason, in WSL, some services start listening on IPv6, PhpStorm included.
Here's a report about it on the WSL tracker: https://github.com/microsoft/WSL/issues/4851
Thank you for sharing your findings!
