55This page lists runtime errors Claude Code displays and how to recover from each one, plus what to check when responses seem off without an error. For installation errors such as `command not found` or TLS failures during setup, see [Troubleshoot installation and login](/docs/en/troubleshoot-install).

7Except for [Wrapper and IDE errors](#wrapper-and-ide-errors), which the launching program prints rather than Claude Code itself, these errors and recovery commands apply across the CLI, the [Desktop app](/docs/en/desktop), and [Claude Code on the web](/docs/en/claude-code-on-the-web), since all three wrap the same Claude Code CLI. For other surface-specific issues, see the troubleshooting section on that surface's page.

For the raw HTTP status code definitions, see the [Claude Platform error reference](https://platform.claude.com/docs/en/api/errors).
