What issue are you seeing?

After removing the Codex mobile/remote connection, the old Codex host still appears in the ChatGPT mobile app's Codex area as offline, with a last seen timestamp from several days ago. Tapping reconnect does not restore the connection, and there does not appear to be a way to remove the stale offline host/device entry from either the mobile app or Codex Desktop.

This leaves the mobile connection in a stuck state: the previous host remains account-side, but the user cannot reconnect it or remove it cleanly to pair again.

Steps to reproduce

1. Pair Codex Desktop with ChatGPT mobile using the Codex mobile setup flow.
2. Remove or disconnect the Codex mobile connection.
3. Open ChatGPT mobile and go to Codex.
4. Observe that the host/device still appears as offline with an old last seen timestamp.
5. Try to reconnect or remove the stale entry.

Actual behavior

• The host remains visible as offline in ChatGPT mobile Codex.
• The stale entry shows an old last seen timestamp.
• Reconnect does not work.
• No clear UI exists to remove the stale offline host/device.
• Restarting Codex Desktop and attempting a fresh mobile setup does not clear the stale entry.

Expected behavior

One of the following should be possible:

• The stale offline host can be removed from ChatGPT mobile Codex.
• The host can be re-paired cleanly from Codex Desktop.
• Codex Desktop Settings > Connections can revoke/clear the account-side stale mobile/host registration.
• The product provides a documented reset flow for stale Codex mobile remote hosts.

Troubleshooting already tried

• Confirmed Codex Desktop and ChatGPT mobile are on the same account/workspace.
• Restarted Codex Desktop and ChatGPT mobile.
• Tried starting a fresh Set up Codex mobile flow from the Desktop app.
• Checked Codex Desktop Settings > Connections for a removable stale device entry.
• Looked for an obvious local removable Codex Desktop registry/state entry, but the stale offline host appears to be account-side rather than a simple local cache entry.

Notes

There are community reports of similar behavior where a host remains linked to the account, appears offline in mobile, and Reconnect does nothing, with no visible way to fully remove/reset it. It would be helpful to have either a product fix or a documented support-side cleanup path for stale Codex mobile remote host registrations.
