could not build HTTP client for Ollama probe: {e}

Error message

could not build HTTP client for Ollama probe: {e}

What it means

Doctor embedding-model probe: reqwest::blocking::Client::builder() with a 3s timeout failed to build, so the Ollama reachability check at {base_url}/api/tags cannot even be attempted. This is a client-construction failure (typically TLS backend init or system resource limits), not an Ollama-side problem — the probe aborts without drawing conclusions about the daemon.

Solutions

1. Retry the doctor — transient resource exhaustion can make client init fail once
2. Check system TLS setup (root store, native-tls backend) if the failure is persistent
3. Probe Ollama manually with curl {base_url}/api/tags to confirm the daemon independently
