Hi there,

This is continuation to the previous post I made http://www.mqseries.net/phpBB2/viewtopic.php?p=438538#438538

I unabled JSSE trace on the integration server as I was getting the below ssl handshake error

BIP3152S: Socket error detected whilst invoking Web service located at host arlibmcdq002 port 9443, path ***. BIP3165S: An error occurred whilst performing an SSL socket operation. Operation: connect. Error Text: SSLException: readHandshakeRecord. "

From the trace it looks like that the issue is with the cipher mismatch .
Ciphers at the ACE side :
ssl-enum-ciphers:
| SSLv3: No supported ciphers found
| TLSv1.2:
| ciphers:
| TLS_RSA_WITH_AES_128_CBC_SHA - strong
| TLS_RSA_WITH_AES_128_CBC_SHA256 - strong
| TLS_RSA_WITH_AES_128_CCM - strong
| TLS_RSA_WITH_AES_128_CCM_8 - strong
| TLS_RSA_WITH_AES_128_GCM_SHA256 - strong
| TLS_RSA_WITH_AES_256_CBC_SHA - strong
| TLS_RSA_WITH_AES_256_CBC_SHA256 - strong
| TLS_RSA_WITH_AES_256_CCM - strong
| TLS_RSA_WITH_AES_256_CCM_8 - strong
| TLS_RSA_WITH_AES_256_GCM_SHA384 - strong
| TLS_RSA_WITH_ARIA_128_GCM_SHA256 - strong
| TLS_RSA_WITH_ARIA_256_GCM_SHA384 - strong
| TLS_RSA_WITH_CAMELLIA_128_CBC_SHA - strong
| TLS_RSA_WITH_CAMELLIA_128_CBC_SHA256 - strong
| TLS_RSA_WITH_CAMELLIA_256_CBC_SHA - strong
| TLS_RSA_WITH_CAMELLIA_256_CBC_SHA256 - strong

Ciphers on the server side :
| ciphers:
| TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 - strong
| TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 - strong

How can I add the ciphers on the server side to the client side ?

hi...what version of ACE/IBM Java are you using as the current cipher list seems to be bit restrictive

https://www.ibm.com/docs/en/app-connect/11.0.0?topic=infrastructure-ssl-cipher-suites
https://www.ibm.com/docs/en/sdk-java-technology/8?topic=suites-cipher

The ACE V11/IBM Java 8 do include more ciphers including the ones you are after,

*ECDHE_RSA_WITH_AES_128_GCM_SHA256
*ECDHE_RSA_WITH_AES_256_GCM_SHA384

So have a review of the current enabled/disabled cipher suites with the current config and the reasons for it
