request to {url} failed: {e}

Error message

request to {url} failed: {e}

What it means

A reqwest send failure while POSTing a multipart form in the cube-cli HTTP client: the request to the composed URL never completed (DNS failure, connection refused, TLS error, timeout). This is the TransportError path — the server was not necessarily reached at all, distinguishing it from an HTTP error status.

Solutions

1. Verify the base URL and network connectivity to the Cube endpoint
2. Check for proxy, DNS, or TLS configuration issues in the CLI environment
3. Retry the command — transient network failures often clear on their own
