> When a consumer encounters an issue that triggers marking a coordinator as unknown, the error message it prints does not give context about the error that triggered it.
> {noformat}
> log.info("Group coordinator {} is unavailable or invalid, will attempt rediscovery", this.coordinator);{noformat}
> These may be triggered by response errors or the coordinator becoming disconnected. We should improve this error message to make the cause clear.
