Separate connectivity from location eligibility
Check status.claude.com before changing network settings. Match your actual location against the official supported list. IP classification or a WebRTC result alone does not diagnose a Claude restriction.

Use documented enterprise proxy settings
Claude Code supports HTTP_PROXY and HTTPS_PROXY for authorized HTTP/HTTPS proxies. Ask your network administrator for the endpoint and required trust configuration; avoid putting passwords in shared scripts. The network documentation says SOCKS proxies are unsupported.
Check TLS and report the exact error
Use the official network guide for certificate trust and domain access. Do not disable certificate verification to make a failing connection work. Capture the exact error and timestamp, with secrets redacted, for your administrator or support.

Frequently asked questions
Does a residential IP guarantee access?
No. Network labels do not establish supported-location, account or billing eligibility.
Must I change WebRTC settings to use Claude Code?
Do not assume a WebRTC test explains a CLI error. Use the documented proxy, TLS and error checks.
