Failed to create HTTP client

Error message

Failed to create HTTP client: {}

What it means

Returned by download_model_detailed when reqwest::Client::builder()...build() fails. The builder here sets tcp_nodelay, a 1-hour total timeout, a 30-second connect timeout, and a connection pool; build() practically only fails when the TLS backend cannot initialize (certificate store/proxy configuration problems) or the builder options are invalid for the environment.

Solutions

1. Restart the app once - transient TLS init failures sometimes clear on a fresh process
2. Unset or fix HTTP_PROXY/HTTPS_PROXY/ALL_PROXY environment variables if they reference dead or malformed proxy URLs
3. On Linux, ensure the system CA certificate store is installed and healthy (update-ca-certificates / ca-certificates package)
4. Report the inner error text with the issue - the '{}' carries reqwest's reason and pinpoints the subsystem

match engine.download_model(name, None).await {
    Err(e) if e.to_string().contains("Failed to create HTTP client") => {
        // environment problem (TLS/proxy): prompt restart, ask user to check proxy env vars,
        // and report the inner reqwest error - retrying unchanged will not help
        return Err(anyhow!("network stack unavailable: {e}"));
    }
    other => other?,
}

When it happens

Trigger: Building the client on a machine where the TLS backend fails to initialize (broken system trust store, missing root certificates in a minimal container); environment proxy variables (HTTP_PROXY/HTTPS_PROXY/ALL_PROXY) pointing at an invalid URI in setups where reqwest picks them up; extremely constrained environments where allocating the pool or timers fails.

Common situations: Corporate MITM proxy with custom env configuration; running the desktop app in a hardened/minimal OS or container without ca-certificates; leftover proxy env vars from a VPN client.
