Error message

request to {} failed: {}

What it means

The generic TransportError of the cube-cli HTTP client: the underlying reqwest send for the HTTP request failed before a response was received (connection refused, DNS failure, timeout, TLS problem). The {} placeholders carry the method/URL and the reqwest error chain. Note the CLI already sets Content-Length: 0 for bodyless writes to avoid spurious 411s, so this error points at connectivity rather than framing.

Solutions

1. Confirm the target URL is correct and the server is reachable
2. Check DNS resolution, proxies, VPN, and TLS settings in the CLI environment
3. Retry — transient network errors are a common cause
