claude-code - 💡(How to fix) Fix [Bug] Anthropic API Error: Socket connection closed unexpectedly [1 comments, 2 participants]

API Error: The socket connection was closed unexpectedly. For more information, pass [{"error":"The socket connection was closed unexpectedly. For more information, pass verbose: true in the second argument to fetch()","timestamp":"2026-05-23T13:00:54.754Z"}]

TL;DR

Pass verbose: true in the second argument to fetch() to gather more information about the API error.

Guidance

• The error message suggests a premature close of the socket connection, which may indicate a network issue or a problem with the server.
• To mitigate the issue, try passing verbose: true in the fetch() call to get more detailed error information.
• Verify that the API endpoint is correctly configured and accessible.
• Check the network connection stability to ensure it's not causing the premature close.
