[BUG] Frequent ECONNRESET Disconnections While Other Network Applications Work Normally

Preflight Checklist

• I have searched existing issues and this hasn't been reported yet
• This is a single bug report (please file separate reports for different bugs)
• I am using the latest version of Claude Code

What's Wrong?

Description
The application repeatedly disconnects with an ECONNRESET error while generating responses or maintaining an active session. The issue is isolated to the Claude integration/CLI, as all other network-dependent applications on the same machine and network continue to function normally without packet loss or connectivity drops.

Error Log / Screenshots
Plaintext
API Error: Connection dropped (ECONNRESET)

What Should Happen?

Expected Behavior
The session should maintain a stable connection or gracefully retry/resume streams when handling long completions without throwing ECONNRESET drops.

Just open Claude and send message it will start flickering and disconnecting so furstrating keeps on delaying my tasks I may consider cancelling subscriptions if this keep on going

Additional Information

No response

Start with the ECONNRESET reproduction in Claude Code 2.1.272 on macOS using Terminal.app, and inspect the connection behavior while generating responses or maintaining an active session. Compare the behavior with the previous working version if available; done means long completions maintain a stable connection or gracefully retry/resume streams without disconnecting.
