Hey, thanks for the report. Good news: in the logs, the model finished all the work for this request successfully on the server. The client connection is what drops near the end of the turn. The Stream ended without turnEnded — connection likely dropped mid-stream error is transient and means the HTTP/2 stream closed before completion. On long, complex tasks with Fable 5 High, the stream stays open longer, so it’s more likely to get interrupted by a VPN, a corporate proxy, or an unstable network.
What to try:
If you’re on a VPN or behind a corporate proxy like Zscaler, open App Settings Cmd+,, find HTTP/2, and switch to HTTP/1.1. This is often the cause of drops on long streams.
Run Cursor Settings > Network > Run Diagnostics and check if it shows any clear connection issues.
Update Cursor. You’re on 3.10.20, and newer versions improved retry behavior when a stream drops.
Let me know if this helps, especially switching off HTTP/2. If the drops continue, please share a couple more Request IDs from fresh attempts.
