Kafka inter broker SSL handshake failed - ssl

I am trying to setup inter-broker SSL (not client) authentication and keep seeing the following errors:
[2019-05-17 06:33:47,151] INFO [Controller id=1004, targetBrokerId=1004] Failed authentication with /$IP (SSL handshake failed) (org.apache.kafka.common.network.Selector)

[2019-05-17 06:33:47,151] ERROR [Controller id=1004, targetBrokerId=1004] Connection to node 1004 (/$IP:9093) failed authentication due to: SSL handshake failed (org.apache.kafka.clients.NetworkClient)
My server.properties is:
listeners=PLAINTEXT://$IP:9092,SSL://$IP:9093
security.inter.broker.protocol=SSL
ssl.truststore.password=$PASS
ssl.keystore.password=$PASS
ssl.key.password=$PASS
ssl.endpoint.identification.algorithm=""
ssl.keystore.location=/etc/kafka/kafka.server.keystore.jks
ssl.truststore.location=/etc/kafka/kafka.server.truststore.jks
``
When I run `openssl s_client -debug -connect $IP:9093 -tls1` I get back a list of certificates and `Secure Renegotiation IS supported`
Despite adding `-Djavax.net.debug=all` there's not anything in the logs which points to the problem.
Kafka version 2.2
Any ideas?

I had incorrectly set the value of ssl.endpoint.identification.algorithm="" instead of ssl.endpoint.identification.algorithm", this fixed it.
This value was changed in 2.2 to default to https so setting it to nothing worked.

Kafka Broker Failed authentication - SSL handshake failed

Elsewhere in the log of another cluster member, authentication succeeds. So why does it work between different nodes, but not from one node to itself?

I have solved the issue by moving the SSL listener away from the default port of 9092.
This leaves me with a different question: if I have configured only one listener, with SSL, on port 9092, why is there any PLAINTEXT activity on that same port?
The errors shown above were caused by each broker trying to connect to itself on port 9092, probably using PLAINTEXT, even though I had configured only SSL.
Also: what is the difference between settings (1) and (2) below?
# (1) The address the socket server listens on. It will get the value returned from
# java.net.InetAddress.getCanonicalHostName() if not configured.
# FORMAT:
# listeners = listener_name://host_name:port
# EXAMPLE:
# listeners = PLAINTEXT://your.host.name:9092
#listeners=PLAINTEXT://:9092
listeners=SSL://$auto_host:9092
# (2) The port the socket server listens on
port=9092

JMeter JMS: Getting Error: Failed to connect via SSL to [ssl://<server-name>:7352]: Received fatal alert: protocol_version

I tried:

It gave the following output:
SSL-Session:

Cipher : ECDHE-RSA-AES256-GCM-SHA384
Session-ID:
Session-ID-ctx:
So added the following line in jmeter.properties file.
https.default.protocol=TLSv1.2
Also commented jdk.tls.disabledAlgorithms from java.security file for JDK (I'm using jdk1.8.0_291)
# jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA, \
# DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
# include jdk.disabled.namedCurves
But still I'm getting the same error. Someone please help.
I think you're using the wrong property (not only the wrong property but the wrong place as well), you're setting default protocol for HTTPS, while you need to set it for TLS, i.e. add the next line to system.properties file
jdk.tls.client.protocols=TLSv1.2
JMeter restart will be required to apply this property.
If it won't help or you will get different errors - consider adding the next line there as well:
javax.net.debug=all
and then check jmeter.log file and stdout for any suspicious entries
More information:

Apache JMeter Properties Customization Guide
I resolved it by using the latest tibjms.jar in the lib directory in JMeter as the Tibco server was upgraded some hours before I raised this issue.

ERROR [Producer clientId=console-producer] Connection to node -1 (/myip-address:9096) failed authentication due to: SSL handshake failed

I have a distributed kafka with 3 brokers that have port numbers 9093, 9094, 9095 and I added the SSL with port numbers 9096, 9097, 9098.
I am getting the following error when I run the producer client:
[2020-06-15 10:08:07,892] ERROR [Producer clientId=console-producer] Connection to node -1 (/myip-address:9096) failed authentication due to: SSL handshake failed (org.apache.kafka.clients.NetworkClient)

I have tried to use: ssl.endpoint.identification.algorithm= but that did not solve the problem for me.
I am using Kafka 2.5
I can share my config files if need be.
What else could I try to troubleshoot this issue?
Thank you.
I was able to solve this issue by simply using my
domain-name:9096,domain-name:9097,domain-name:9098
instead of:
my-ip-address:9096,my-ip-address:9097,my-ip-address:9098
So, using the actual domain name is important due to the certificate being created with the domain name.

RabbitMQ Server TLS, client alert: Fatal - Certificate Unknown when starting service

Have RabbitMQ configured to enable TLS with certificates. Key, Cert, and CA defined in .conf file. Upon service startup, error is thrown. Cannot find the cause for this to be thrown and logging isn't giving any more information at the debug level.
Get a client alert failure and am not certain of cause.

Our certs didn't have the correct type of X509v3 Extended Key Usage on the cert.
For x509 Auth, you'll need to assign client web auth when creating the certificate.
X509v3 Extended Key Usage:
TLS Web Client Authentication
This won't fix the issue if your certificate CA is broken and can't be verified, but for my issue, this was the resolution.

WARN Failed to send SSL Close message(Kafka SSL configuration issue)

I have done broker and client configuration on same node.
When ssl.client.auth=none it works fine but whenever I change that property to "required", ssl.client.auth=required and enabled security.inter.broker.protocol=SSL then it gives me an issue on producer side.

Any solution for this?
As mentioned in the comments, the answer was found by the asker:
Its resolved.This issue comes when signed certificate of the server
did not match with client keystore. We need to generate client
keystore and import the the signed certificate of the server to client
keystore.
