Describe the Bug

:lady_beetle: Bug Description

When sending a message in Cursor chat (Ask or Agent mode), the input text disappears but no output is returned. The chat panel stays empty.

:high_voltage: Expected Behavior

After pressing Enter (or clicking the green send button), the selected model (e.g., GPT-5, Claude-Sonnet) should process the input and return a response in the chat panel.

:red_circle: Actual Behavior

Input disappears after sending.

No response appears.

Developer console shows errors like:

[Background Composer] timed out getting tasks from agent
[Background Composer] preferred remote not found

.cursor-server process uses very high CPU.

On htop, multiple .cursor-server tasks are running at the same time, consuming resources.

:test_tube: Steps to Reproduce

Open Cursor (Pro plan).

Create a new chat (Ask mode, GPT-5 or Claude).

Type hi and send.

Observe: text disappears, no response comes back.

Yes - Cursor is unusable

Hey, thanks for the report. It looks like a network issue that’s preventing streaming responses from reaching the client.

Please try:

  • Run network diagnostics: Cursor Settings → Network → Run Diagnostic, then share any errors
  • Enable HTTP 1.1 fallback: Cursor Settings → Network → enable HTTP 1.1 (or “Disable HTTP/2”).
  • Test on a different network: if possible, try a mobile hotspot to check if it’s ISP‑related
  • Open DevTools and check the console/network tabs for errors

Let me know the diagnostic results and whether switching to HTTP 1.1 helps.
