Locate the failing layer first
A Claude Code request can traverse the local terminal, environment variables, proxy client or library, DNS, the exit network, TLS and the destination service. Any layer can surface as a timeout or reset. Keep the same exit and test resolution, handshake and destination response separately instead of repeatedly changing IPs.
LyProxy can provide static residential IPs and HTTP/SOCKS5 access. Countries, routes, authentication format, stock and pricing are dynamic. Anthropic product support, account rules and regional policies remain governed by Anthropic's official documentation.
Mapping LyProxy product facts to Claude Code configuration
For a terminal tool such as Claude Code, the critical product fields are the proxy host, port, authentication, protocol, exit country and term—not marketing adjectives. A static residential IP reduces network variation in a persistent development environment. If the client explicitly supports only HTTP proxying, use that compatible path instead of forcing SOCKS5 merely because it is offered.
LyProxy delivers the network exit and credentials. Whether the tool reads environment variables, supports remote DNS, the account has permission and the Anthropic service is healthy belong to the client, account and third-party layers respectively. Clear responsibility boundaries let support and engineering diagnose with evidence instead of attributing every error to the proxy.
Configuration-path comparison
| Path | Fit | Advantage | Common failure | Validation |
|---|---|---|---|---|
| HTTP/HTTPS environment variables | Runtime explicitly supports HTTP proxies | Straightforward and observable | Variables not inherited or auth not encoded | Inspect variables and request the destination in the same shell |
| SOCKS5 / ALL_PROXY | Client or wrapper explicitly supports it | Fits more TCP workflows | DNS remains local or socks5h unsupported | Test local and remote DNS separately |
| System proxy client | Several tools share one exit | Central rule management | Split-routing, TUN or DNS conflict | Inspect matched rule and exit IP |
| Fixed static residential exit | Long-running development and repeatable diagnostics | Fewer changing variables | Mistaking account issues for network issues | Keep direct/proxy comparison evidence |
A 10-minute layered diagnostic
- Confirm the proxy variables in the same terminal, encode special characters in credentials, and verify that child processes inherit them.
- Request a public exit-check endpoint, then the official Anthropic destination. Record DNS, connection, TLS, HTTP status and total time separately.
- Compare direct, HTTP proxy and SOCKS5 paths. If only one protocol fails, inspect client support and DNS mode before changing the account or exit.
- Keep the command, time, exit, error code and response headers. Remove tokens, passwords and proxy credentials before sharing logs.
Separate network, account and service state
A successful connection proves only that the network path reached the destination. It does not prove account permission, regional support, quota or service health.
For 401/403, inspect the token, account, organization and official regional policy. For DNS, connection or TLS errors, focus on the network layer.
Keep proxy credentials in secret management. Do not commit them, include them in screenshots or expose them in public tickets or frontend files.

Frequently asked questions
Does Claude Code require SOCKS5?
No. Use a proxy path the runtime explicitly supports. HTTP/HTTPS variables are often easier to observe; SOCKS5 requires client and DNS-mode support.
Why does the browser work while Claude Code times out?
The browser and terminal may use different proxy rules, DNS or certificate paths. Test inside the same terminal that runs Claude Code.
What is the difference between SOCKS5 and socks5h?
In common clients, socks5h resolves the hostname through the proxy. Exact support depends on the client.
Does 401/403 prove the proxy is broken?
No. Inspect the token, account permission, organization, region policy and destination response first.
What should a diagnostic log contain?
Keep time, protocol, exit market, DNS/connection/TLS/HTTP stage, error code and duration. Remove every credential before sharing.
