Proposed fix: [Kafka Java clients / Spring Kafka / Kafka Connect] WARN loop 'Connection to node -1 (localhost/127.0.0.1:9092) could not be established. Node may not be available.' (<= 3.6: 'Broker may

Recommended action: If node -1: verify bootstrap.servers, port mapping, and that the listener speaks the expected protocol; if node N>=0: fix advertised.listeners for the client's network (see dual-listener setup). 'No resolvable bootstrap urls' means DNS for every bootstrap host failed.
Option: Read the node id first [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. node -1/-2…: fix bootstrap.servers / port / broker startup
2. node >= 0: fix advertised.listeners so the returned host:port is reachable
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
