Codex extension in vscode over ssh to windows busted with update

Resolved 💬 0 comments Opened Aug 27, 2026 by jonkatz6 Closed Aug 27, 2026

After updating the official OpenAI Codex VS Code extension to version
26.820.71523, the extension fails to activate when installed on a
Windows host accessed through VS Code Remote SSH.

VS Code reports:

Activating extension 'openai.chatgpt' failed:
Cannot find module
'\.vscode-server\extensions\
openai.chatgpt-26.820.71523-win32-x64\out\extension.js'

Require stack:
\.vscode-server\cli\servers\
Stable-08d4889f9ec4a1685d257b9b95de036c8e1ce1e5\
server\out\vs\workbench\api\node\extensionHostProcess.js

Environment:

  • VS Code: 1.135.0
  • Remote: ssh-remote
  • Remote OS: Windows
  • Extension host: workspace
  • Codex extension: 26.820.71523
  • Extension path:

\.vscode-server\extensions\
openai.chatgpt-26.820.71523-win32-x64

Troubleshooting performed:

  1. Uninstalled the Codex extension from the remote SSH host.
  2. Reinstalled the current version from the VS Code extension marketplace.
  3. The freshly installed copy produced the identical missing

out\extension.js error.

  1. Used "Install Another Version..." and installed the immediately

preceding Codex extension release.

  1. The preceding release works normally on the same VS Code installation,

same Windows SSH host, same workspace, and same Codex CLI configuration.

The standalone Codex CLI/app-server also continues to initialize correctly:

C:\nvm4w\nodejs\codex.cmd
app-server initialized successfully.

Expected behavior:

The current Codex extension should activate on the Windows Remote SSH
extension host as the immediately preceding release does.

Workaround:

Downgrading the Codex VS Code extension to the immediately preceding
release fixes the problem.
