910910* A `CLAUDE_CODE_USE_*` provider variable, such as `CLAUDE_CODE_USE_BEDROCK` for [Amazon Bedrock](/docs/en/amazon-bedrock) or `CLAUDE_CODE_USE_VERTEX` for [Google Cloud's Agent Platform](/docs/en/google-vertex-ai)
911911* [`ANTHROPIC_BASE_URL`](/docs/en/env-vars) pointing at a host other than `api.anthropic.com`, such as an [LLM gateway](/docs/en/llm-gateway) or proxy, even when you sign in with claude.ai; before v2.1.196, a custom base URL didn't block Remote Control
912* `ANTHROPIC_UNIX_SOCKET` set, so the session sends its requests through a local socket rather than to `api.anthropic.com`
912913* An enterprise [cloud gateway](/docs/en/claude-apps-gateway) sign-in made through `/login`, which doesn't support Remote Control and has no variable to unset

13831384Before v2.1.234, the message ended after `intercepting the request`.
13841385 
1386Before v2.1.271, a reply that carried a valid API message under a non-JSON content type such as `text/plain` also ended the turn with this error. Some LLM gateways use that content type for the non-streaming reply.

13851388**What to do:**
13861389 
13871390* Read the `Response:` clause to see which system answered. An HTML body, no Anthropic request id, or a named server such as `nginx` or `cloudflare` means that something between Claude Code and the API replied in its place
