What's Wrong?

After upgrading Claude Code from 2.1.110 to 2.1.122, two issues occur:

  1. API connections fail with API Error: Unable to connect to API (ConnectionRefused)
  2. Image recognition is also broken

What Should Happen?

Downgrading to 2.1.110 resolves both issues: npm install -g @anthropic-ai/[email protected] Same configuration works in 2.1.110 Network connectivity is fine (ping works, DNS resolves)

extent analysis

TL;DR

Downgrade to Claude Code version 2.1.110 to resolve API connection and image recognition issues.

Guidance

  • Verify that the issue is indeed related to the version upgrade by checking if downgrading to 2.1.110 resolves the problem.
  • Check the API Base URL configuration to ensure it is correct and the API is reachable.
  • Review the environment variables, such as ANTHROPIC_AUTH_TOKEN and ANTHROPIC_BASE_URL, to ensure they are properly set.
  • Consider reporting the issue to the developers to investigate and fix the regression in version 2.1.122.

Notes

The issue seems to be a regression introduced in version 2.1.122, and downgrading to 2.1.110 is a temporary workaround. However, it is essential to report the issue to the developers to ensure a proper fix is implemented in future versions.

Recommendation

Apply workaround: Downgrade to version 2.1.110, as it is the last known working version, and report the issue to the developers for further investigation and resolution.
