Additional Information

I am running on Windows 10 Pro, Version 10.0.19045 Build 19045.

Latest IDE versions tested: GoLand 2025.3.4 (253.32098.60) and PhpStorm 2025.3.4 (253.32098.40)

WSL version:

WSL version: 2.6.3.0
Kernel version: 6.6.87.2-1
WSLg version: 1.0.71
MSRDC version: 1.2.6353
Direct3D version: 1.611.1-81528511
DXCore version: 10.0.26100.1-240331-1435.ge-release
Windows version: 10.0.19045.6575

Claude Code was tried in Ubuntu 24.04 LTS and Ubuntu 25.10 WSL2 instances, same issue in both.

I have added the firewall rule for my WSL2 IP range (172.22.0.0/16) and I have tried restarting IDE, WSL2 and the entire PC multiple times, nothing helped.

WSL2 networking mode is set to NAT, I tried mirrored, but that broke other things, so I would like to keep it in NAT mode.

Remote development version works, but that is quite uncomfortable to use. Also on a second PC which runs native Ubuntu everything works, so this is a WSL2 specific issue.
