Error 13/13 brokers are down

We are running Kafka 3.1.0 on Kubernetes using Strimzi and a C#(.NET) client that is connecting to this cluster. When the messages are published to the topic, the error message, “13/13 brokers are down”, getting reported randomly (i.e. we see this error only during some writes). There is no data loss - messages are visible on the target topic. The Confluent client library version is 2.4.0. Any ideas or suggestions would be greatly appreciated. Thanks.


producer = new ProducerBuilder<string, string>(producerConfig)
.SetLogHandler((
, l) =>
{
EventLog.WriteEntry(Common.eventLogAlert, $“Create Producer [{l.Level}] : [{l.Message}]”, EventLogEntryType.Information, Common.eventIDThrottlingAlert);
})
.SetErrorHandler((_, error) =>
{

                EventLog.WriteEntry(Common.eventLogKafkaProduceAlert, $"Failed to build Kafka producer due to error : {error}", EventLogEntryType.Warning, Common.eventIDThrottlerKafkaProducerAlert);
        })
        .Build();
