Hi everyone,
could you please advise how to fix the problem below ?
I'm trying to run Zookeeper with mTLS to authenticate Kafka broker on Zookeeper
by SSL certificate.
Both Zookeeper and Kafka broker are located on the same server, so I use the
same keystore and trustore for them.
Here is the error in Kafka server.log when Kafka starts:
