It now says the response came from a network intermediary, not Anthropic, and suggests checking your network's proxy. A network intermediary is something between you and Anthropic, such as a corporate proxy or firewall. Other 4xx errors still show the generic text.\n\n**Why**\n\nIf you are behind a proxy, it is now easier to see that the failure comes from your network rather than from Anthropic.\n\n- Area: API\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: both\n- Heads-up: no"}
