Bug Report: Project returns 503 error – unable to send or receive messages for over 12 days
`Steps to Reproduce`
- Open any ChatGPT project in my account (multiple projects affected).
- Attempt to send or receive any message via the interface (tested in app, browser, and incognito).
- Every request results in a 503 error, regardless of device, browser, or network environment.
- Issue persists across different devices, networks, and after clearing cache/cookies.
- Other accounts (including a secondary one I own) can use projects normally from the same environment.
`Expected Result`
Messages should be sent and received normally within any ChatGPT project, as usual.
`Actual Result`
All projects under this account consistently return a 503 error when sending or receiving messages.
Error persists for 12+ days.
Both web and mobile apps affected.
No workaround found (clearing cache, switching networks, reinstalling app all failed).
No issue for other accounts on the same devices/networks.
