C#.NET Confluent Kafka Error: Disconnected (after XYZms in state UP)

[ShaibalKantiShil]

Description

Application connects properly with the Kafka broker.
But, sometimes, we get an error similar to:
“Disconnected (after XYZms in state UP)”
Once this error is thrown, the Kafka consumer stops polling Kafka.
The error is not re-tried automatically.

How to reproduce

Unsure.
This error happens randomly.
