Troubleshooting
Problem
Using the DWC connected to an engine z/OS and a Liberty server 24.0.0.8 or higher,
is not possible to access to the workload designer. Looking in the message.log file a message like this will be appear:
CWPKI0824E: SSL HANDSHAKE FAILURE: Host name verification error while connecting to host [localhost]
Resolving The Problem
- Stop the application server
- Open the file dwc_installation_dir/usr/servers/dwcServer/configDropins/default/ssl_config.xml and modify the line twaSSLsettings:
- Change from:
<ssl id="twaSSLSettings" keyStoreRef="twaKeyStore" trustStoreRef="twaTrustStore" sslProtocol="TLSv1.2" clientAuthenticationSupported="true"/>
to
<ssl id="twaSSLSettings" keyStoreRef="twaKeyStore" trustStoreRef="twaTrustStore" sslProtocol="TLSv1.2" clientAuthenticationSupported="true" verifyHostname="false"/>
- Start the application server and re-run the scenario
