Stale ANTHROPIC_BASE_URL Produces Misleading Connection-Refused Error
When a stale ANTHROPIC_BASE_URL environment variable points to a dead local endpoint, Claude Code fails instantly with a generic connection-refused error, while standard diagnostics like curl and raw fetch succeed because they don't read that variable, leaving users no clear diagnostic path to the true root cause.

Similar Problems
surfaced semanticallyClaude Cowork Desktop Unusable in Corporate Environments Without Proxy
The Claude Cowork desktop app runs in an isolated VM with no awareness of host-system proxy configuration, causing all API calls to fail silently in corporate networks behind HTTP/HTTPS proxies. Unlike Claude Code CLI which supports standard proxy environment variables, Cowork provides no mechanism to configure or inherit proxy settings, completely blocking enterprise adoption.
Client Ignores Custom ANTHROPIC_BASE_URL for Self-Hosted Models
Users want a setting to point an AI client at a self-hosted or third-party model endpoint, but the app keeps using the default Anthropic URL even when the environment setting is changed. This blocks use of alternative hosted models.
Intermittent GitHub Connectivity Blocks CLI Login on Managed Cloud Computer
A managed cloud Linux environment intermittently cannot reach GitHub, causing connection-refused errors during GitHub CLI device login. Git workflows depending on that login are blocked.
Docker Desktop Strips Proxy Credentials on Manual Proxy Configuration
Developers behind authenticated corporate proxies find Docker Desktop fails to pull images even after configuring proxy settings via UI, environment variables, and daemon.json — with manual proxy configuration silently stripping the username and password on save. This leaves engineers on proxied networks unable to pull images through any documented configuration path.
