We tested version 9.10 ,JDK 1.8, send message by TN use TLS 1.2 protocol, send failure, according to Alert Fatal: handshake failure;
When using TLS 1.0 protocol, can correct to send and receive messages. Who know where is wrong?

Sounds like certificate issue to me. Make sure if required keys (public key) added to keystores/truststores

Hello Sherry,

From the error message it looks like your target system is not accepting TLS1.2

Can you please check once?

Thanks,
Yogesh

Hi,

please note that TLS v1.1 and TLS v1.2 are only available when using JSSE for inbound or outbound connections.

When JSSE is not used only TLS v1.0 will be available.

This is due to the fact that the properties watt.net.ssl.client.handshake.minVersion=tls and watt.net.ssl.client.handshake.maxVersion=tls will both using TLS v1.0. The underlying Entrust library is not yet aware of the newer TLS v1.1.and TLS v1.2 protocol version.

Addnedum please check for the following wiki ariticle:
https://techcommunity.softwareag.com/pwiki/-/wiki/Main/Debugging+TLS+SSL+connections+in+Integration+Server

This explains how to debug and which versions are supported by each library (Entrust IAIK or JSSE):

Holger

Keystores/truststores configuration is correct. Because TLS1.0 can send success.

Delete all settings similar to iaik, or reported the following error. Why to enable iaik?

Delivery service for 5972sa00bf6ora5m0000000q failed with a status of fail and status message of ERROR iaik.security.ssl.SSLException: Peer sent alert: Alert Fatal: handshake failure
