failed to build shared SearXNG HTTP client

Error message

failed to build shared SearXNG HTTP client

What it means

Panic payload inside shared_http_client(): the SearXNG tool lazily builds one process-wide reqwest client in a OnceLock (platform TLS backend + timeouts). A build failure here is environment-level (TLS/proxy) and, because it happens inside get_or_init on first use (from new()), it poisons the OnceLock and permanently disables SearXNG search for the process.

Solutions

1. Check TLS backend availability and proxy configuration on the host
2. Restart the process after fixing the environment — the OnceLock stays poisoned for the process lifetime
3. Avoid .expect inside get_or_init; store a Result so later callers can retry or degrade
