         @Kbediako I found the cause: it was due to Proxifier being installed on my Windows. Disabling it resolved the issue.  |

         I asked Codex (gpt5-high) to create a simple browser extension in an empty folder ( That also seems to fail because of permission issues. VS Code itself can create files just fine (via UI and terminal). After telling it  Afterwards it realized the file content was not as expected though: It did, and then created a working extension.  |

         0.5.23 is out, but unless I'm missing it there's no changelog and the release page only covers the CLI.  |

         Dear Sir, I need to use a network proxy to access the internet — I believe this is the case for many companies as well. When I remote into other physical machines, Codex works fine. However, only in WSL, even with the same network settings and after trying many methods, Codex still cannot access the network. In contrast, Copilot has never had this issue — as long as I configure the network proxy correctly in VS Code, it works perfectly. There used to be a workaround for this problem, but it no longer works in version 0.4.31 or 0.5.33. Please help fix this issue. Thanks! Thanks  |

Hello! Thanks to all of you who've provided feedback and contributions since the Codex CLI and IDE extension launched. We have a few improvements coming for the IDE Extension on Windows, and we'd love your help testing and improving.
To start, today's prerelease build supports using Windows Subsystem for Linux (WSL2) to run commands in bash, for better performance and fewer approvals with sandboxing.
How to test:
wsl --installas adminchatgpt.runCodexInWindowsSubsystemForLinuxsetting in VSCode SettingsSharing feedback
We'd love to know how this works for you. Please reply to this discussion with your questions and feedback.
Thanks for helping us improve Codex on Windows!
