Steps to Reproduce

I am just having it evaluate and make a plan for some code I need to write for a simple app. It is supposed to be creating a markdown file.

Claude Model

Sonnet (default)

Is this a regression?

I don't know

Last Working Version

No response

Claude Code Version

claude code in chrome

Platform

Anthropic API

Operating System

macOS

Terminal.app (macOS)

Additional Information

I am just using a cloud session in the browser. It has worked fairly well and stable with a few exceptions but now for the past 4-6 hours I continue to get the API error.

extent analysis

TL;DR

The issue can likely be mitigated by adjusting the API timeout settings or retrying the request.

Guidance

  • Verify the stability of the Anthropic API connection to ensure it's not a transient issue.
  • Check if there are any API usage limits or restrictions that might be causing the timeout error.
  • Consider implementing a retry mechanism with a backoff strategy to handle temporary connection issues.
  • If possible, test the API request with a smaller payload or a different Claude model to isolate the issue.

Example

No code snippet is provided as the issue is related to API interaction and not a specific code implementation.

Notes

The root cause of the issue is unclear, and more information about the API and its configuration would be necessary to provide a definitive solution. The provided guidance is based on common issues related to API timeouts and connection stability.

Recommendation

Apply workaround: Implement a retry mechanism with a backoff strategy to handle temporary connection issues, as the root cause of the issue is unclear and adjusting the API timeout settings might not be feasible.
