Complete Guide to Claude Code Proxy Configuration: From Troubleshooting to Practical Tips

This article provides a detailed walkthrough of the complete process for configuring Claude Code proxy on a remote Ubuntu server. The author first shares their experience with a failed WSL installation on Windows, before shifting to a server environment. The article focuses on two proxy configuration approaches: the first uses Clash proxy and SSH port forwarding, which resolved Claude connection issues but encountered MCP service failures; the second approach successfully achieved seamless switching between proxy and non-proxy environments by creating a custom claude-proxy script. The article includes specific command-line operations, environment variable settings, and executable script code, offering practical reference for developers who need to use Claude in restricted network environments.
