What issue are you seeing?

Environment:

Raspberry Pi 5 (ARM64 Linux)
Codex standalone install (rust-v0.131.0)
ChatGPT iOS app
Remote Control enabled
Previously migrated from npm-managed Codex to standalone-managed Codex

Problem: After some time, the Codex node disappears from the ChatGPT mobile app connection list, even though the local daemon and app-server are still running.

Observed behavior:

codex remote-control returns:

{ "status": "alreadyRunning" }

ps aux | grep app-server still shows:

codex app-server --remote-control codex app-server daemon pid-update-loop

Unix socket remains alive:

~/.codex/app-server-control/app-server-control.sock

However, the device no longer appears in the ChatGPT mobile app’s Remote Connections list.

Workaround: The node becomes visible again only after restarting the app-server:

pkill -f app-server codex remote-control

After restart, the output changes to:

{ "status": "bootstrapped", "remoteControlEnabled": true }

and the device immediately reappears in the ChatGPT mobile app.

Observation: This appears to be a mismatch between:

local daemon/app-server liveness
remote relay/discovery registration state

alreadyRunning may not be re-advertising the node to the relay/discovery layer after the registration expires or disconnects.

Additional notes:

The issue was reproduced multiple times.
Local CLI functionality continues to work normally even while the device is missing from the mobile app.
This was observed after migrating from npm-managed Codex to standalone-managed Codex using the official installer.

What steps can reproduce the bug?

Install standalone Codex (rust-v0.131.0) on Raspberry Pi 5 (ARM64 Linux) using the official installer.
Enable remote control: codex remote-control
Confirm the node appears in the ChatGPT iOS app under Remote Connections.
Leave the daemon running for some time (the disconnect happened multiple times during normal use).
Eventually, the device disappears from the ChatGPT mobile app connection list.
On the Raspberry Pi, verify that the daemon is still alive: ps aux | grep app-server

The following processes are still running:
- codex app-server --remote-control
- codex app-server daemon pid-update-loop
Running: codex remote-control

returns: { "status": "alreadyRunning" }

but the device still does not appear in the mobile app.
Restarting the app-server fixes the issue: pkill -f app-server codex remote-control
After restart, the output changes to: { "status": "bootstrapped" }

and the device immediately reappears in the ChatGPT mobile app.

What is the expected behavior?

The remote-control node should remain visible and reconnectable from the ChatGPT mobile app as long as the local app-server daemon is still running.

If the relay/discovery registration expires or disconnects, the daemon should automatically re-advertise itself without requiring a manual app-server restart.

Running: codex remote-control

while the daemon is already alive should also restore remote discoverability if the node has disappeared from the mobile app.

Additional information

Additional observations:

The issue started after migrating from npm-managed Codex to the standalone-managed install using the official installer.
The old npm-managed app-server had to be manually terminated before standalone remote-control worked correctly.
The issue appears to affect only remote discoverability from the ChatGPT mobile app. Local CLI functionality continues to work normally.
The daemon and unix socket remain alive even while the node disappears from the mobile app.
Running inside tmux was initially used, but the same issue was later observed outside tmux as well.
The environment uses Tailscale and mobile app remote access, so network transitions (WiFi/mobile network changes, idle reconnects, etc.) may possibly contribute.
The issue was reproduced multiple times.
