Infinite thinking in Auto mode

Support Bug Reports
5

Hey, this is a known issue. A few users saw the same behavior in Auto mode and Composer 2, especially last night. One of the model providers had an outage, which caused hangs specifically in Auto mode.

As a workaround, try picking a model manually instead of Auto, like claude-4.6-sonnet or gpt-5.4. Based on other reports, this fixes it right away.

Also try:

  1. Disable HTTP/2: open settings.json via Ctrl+Shift+P > Preferences: Open User Settings (JSON) and add:

    "cursor.general.disableHttp2": true

    Then restart Cursor.

  2. If it still happens, send the Request ID right corner chat menu > Copy Request ID so we can check the backend logs.

The team is aware, and your report helps us prioritize. Related thread: Taking longer than expected on Cursor version 3.0.13

Let me know how it goes.
