NotLeaderOrFollowerException

Hi, we have started seeing following error message.

Error message:
org.apache.kafka.common.errors.NotLeaderOrFollowerException: For requests intended only for the leader, this error indicates that the broker is not the current leader. For requests intended for any replica, this error indicates that the broker is not a replica of the topic partition.. Going to request metadata update now

Can you please help us to figgure what is cause of this?
