# data_connector_unavailable

**HTTP status:** 422 (Unprocessable)

**Title:** Data connector unavailable

## Cause

Your connector did not answer in time, answered with an error, or its address is not reachable. Nothing was stored.

## How to fix it

Check that your connector serves its manifest within 8 seconds, then call the check endpoint.

Call the endpoint named below first, then send the request again.

Endpoint: `POST /v2/data-connectors/{id}/check`

Every error carries `requestId` and the `Request-Id` header. Send it when you write to support.
