I’m encountering a `net/http: timeout awaiting response headers` error when using the Quickwit API via `api.fly.io`.

The error occurs specifically on `_msearch` requests with `max_concurrent_shard_requests=256`. It seems the request is being dropped before headers are returned.

Is there a hard timeout on the `api.fly.io` proxy for Quickwit, or should I be looking at my shard concurrency settings?
