Error message

request http://localhost:8084/quit/ e:%r

Solutions

Ignore: quit proceeds regardless.
If the companion should be running, check its logs/port 8084 binding.
Align the hardcoded port with the companion's configured port.

Defensive patterns

Strategy: fallback

Try / catch

try:
    simple_http_client.request('GET','http://localhost:8084/quit/', timeout=1)
except Exception:
    pass  # best-effort; shutdown continues

Prevention

Treat this log as benign on mobile quits.
Verify companion service port if it should be running.

When it happens

Trigger: Quit on a mobile platform when nothing listens on 8084 or it doesn't answer within the 1s timeout.

Common situations: The companion service already exited, was never started, or the port changed. Harmless — shutdown continues via sys_platform.on_quit().
