# SDK_TRANSPORT_TIMEOUT

- Surface: SDK

## Cause

The per-call request timeout elapsed (or the request was aborted) before a response arrived.

## Fix

Increase `timeoutMs` if cold starts are expected, or check connectivity. The underlying abort is on `logger.error`'s `cause`. This is not an HTTP 503 from the server.
