What issue are you seeing?

Codex is failing to start the task environment for this project.

Observed behavior:

  • Error shown: “Couldn’t set up admin sandbox”
  • The previous prompt card keeps blinking / reappearing
  • UI offers: “Use backup sandbox”
  • Task does not proceed normally

Please diagnose and recover the environment for this project. Requested actions:

  1. Retry provisioning the sandbox for the current task

  2. Fall back to the backup sandbox if the primary sandbox fails

  3. Preserve the existing project state and prior prompt context

  4. Report whether the failure is due to:

    • sandbox provisioning
    • auth/session
    • GitHub connection
    • network restriction
    • workspace permission issue

  5. If the environment is corrupted, recreate the sandbox and continue the task without changing project files unexpectedly I’m unable to use Codex because the environment will not start.

Issue:

  • Error: “Couldn’t set up admin sandbox”
  • “Use backup sandbox” also fails
  • I also get a message saying I need to set up an agent box to continue
  • I cannot send messages in the Codex task view

Details:

  • This is happening repeatedly, not just once
  • The previous prompt appears to blink/reappear
  • Please check whether this is a sandbox provisioning, account/session, workspace-permission, or network-side issue

I can provide screenshots/screen recording, timestamp, timezone, and device/browser details.

extent analysis

TL;DR

Retry provisioning the sandbox for the current task and fall back to the backup sandbox if the primary sandbox fails to potentially resolve the "Couldn't set up admin sandbox" error.

Guidance

  • Check the sandbox provisioning process for any issues, as the error message suggests a problem with setting up the admin sandbox.
  • Verify if the issue is related to account/session, workspace permission, or network restrictions by checking the error logs and network connectivity.
  • Attempt to recreate the sandbox and continue the task without changing project files unexpectedly if the environment is corrupted.
  • Consider providing screenshots or screen recordings to help diagnose the issue, as the problem is happening repeatedly.

Example

No specific code snippet can be provided without more information about the Codex App's internal workings.

Notes

The issue may be related to the specific version of the Codex App or the GPT subscription, but without more information, it's difficult to determine the root cause.

Recommendation

Apply the workaround by retrying the sandbox provisioning and falling back to the backup sandbox, as this may resolve the issue without requiring a full diagnosis of the root cause.
