发生场景
Source(s): https://github.com/openai/codex/issues/53840 , https://github.com/openai/codex/issues/53738 Status: reported working by source, not reproduced by us (workaround, not a permanent fix; workaround from openai/codex#53738).
问题
After VS Code updated to 1.141.1, the Codex panel fails to load in Remote WSL. DevTools shows HTTP 401 for the extension's own JS/CSS under ~/.vscode-server/extensions/.../webview/assets/.
报错原文（已脱敏/规范化）
Codex could not start — The extension could not start its user interface. DevTools: HTTP 401 for ~/.vscode-server/extensions/.../webview/assets/*.js|*.css
适用环境
VS Code 1.141.1, Remote WSL (Ubuntu 24.04), Codex VS Code extension.
如何确认是这个问题
DevTools shows 401s for webview assets and the remote authority contains capital letters (e.g. wsl+Ubuntu-24.04).
不是这个问题时 / 边界
The 401s also happen in a window opened this way, or you are not on Remote WSL. (our note: then update the extension and VS Code and look for a newer issue.) Launching with code . from inside WSL keeps breaking until an upstream fix.
根因
The reporter observed that code . run inside WSL produced the remote authority wsl+Ubuntu-24.04 (capital letters, broken), while a lowercase launch worked. The reporter suspects a case-sensitivity bug in Remote WSL's resource handling; this is not an established mechanism.
占位变量
<distro-lowercase>: your WSL distro name in lowercase. <path-to-project-inside-wsl>: project path inside WSL.
修复步骤
Workaround (from openai/codex#53738):
- Close the broken window.
- From Windows PowerShell open the folder with the remote written in lowercase:
code --new-window --remote wsl+<distro-lowercase> <path-to-project-inside-wsl>(e.g.wsl+ubuntu-24.04). → expect:remoteAuthority=wsl+ubuntu-24.04, no 401s, Codex panel loads.
如何验证
DevTools shows remoteAuthority=wsl+<distro-lowercase>, the 401 errors are gone, and the Codex panel loads.
试过没用的办法
Reported in the thread as not helping: reinstalling the extension, an older extension version, reinstalling VS Code Server, clearing caches, a fresh profile, restarting VS Code/WSL.
