Steps to Reproduce

Launch Cursor on either of my devices
Send a prompt to the agent
Error message appears and halts all interaction

Expected Behavior

I use Cursor on both devices but never simultaneously.
The issue occurs on both Mac and Windows.
No VPN or proxy is in use.
Restarting network, reinstalling Cursor, or changing networks has not resolved the issue.

Operating System

Windows 10/11

Current Cursor Version (Menu → About Cursor → Copy)

Version:1.2.4
Windows11

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, which models are you using? Does creating a new chat resolve the issue?

3

no,I tried.

4

Could you let me know which models you are using, and if this happens with another project as well? Also, let me know if you’re using your account on one device?

I solved,buy a cursor pro then start a new chat
