Solace broker connection issue : Channel is closed by peer

PubSub+ Event Broker
,
1

Hi,

I am currently trying to connect to a PubSub+ event broker (version=9.12.1.26) with TLS and client certificate authentication and I am facing an issue right after the TLS handshake:

I am using the following client library for my Java project :


<dependency>
  <groupId>com.solace.spring.boot</groupId>
  <artifactId>solace-java-spring-boot-starter</artifactId>
  <version>5.2.0</version>
</dependency>

And here is an extract of the configuration of my Java client app:


solace:
  java:
    host: tcps://yyyyyyy:yyyyy
    apiProperties:
      AUTHENTICATION_SCHEME: AUTHENTICATION_SCHEME_CLIENT_CERTIFICATE
      SSL_KEY_STORE: file:/path/to/file.p12
      SSL_KEY_STORE_PASSWORD: password
      SSL_KEY_STORE_FORMAT: PKCS12

You will find heareafter an extract of the logs for my client (logs were configured in verbose mode). Do you what could cause this interruption ?

As I said, just before the disconnection happens the TLS handshake seems to be successful and after that a login message is sent by the client lib (SimpleSmfClient::sendLoginRequestAwaitForResponse).

Thanks

Hi,

Finally I found what was happening. I was trying to connect to the AMQP TLS port but both solace-java-spring-boot-starter and solace-jms-spring-boot-starter seem to support only connection to the port corresponding to the SMF service.

That is why the pubsub broker ended the communication right after the beginning of the exchange (protocol mismatch).
