The 'Error in message stream' in ChatGPT means the real-time streaming connection that delivers words to your screen was interrupted mid-response — not that your message was lost. This error appears in roughly 60–70% of cases due to an unstable network connection or a VPN endpoint throttling the persistent connection; switching to a hotspot and disabling VPN resolves it for most users.
