Request to %s failed: %s [Error: %s]

Error message

Request to %s failed: %s [Error: %s]

What it means

After building the /v1/info request, JsonResponse.execute returns a response whose failure status is surfaced by this formatted ClientException: it reports the requested server URL, the HTTP failure description, and the underlying error. It fires when the coordinator cannot be reached or the /v1/info endpoint returns a non-success response (wrong host/port, TLS problem, server error).

Solutions

1. Verify the Presto coordinator host and port are correct and reachable from the client
2. Check TLS/proxy configuration when the error indicates a connection or certificate problem
3. Inspect the embedded Error field for the server-side failure reason and retry transient network failures
