A scenario where we want to disable access to Release Automation port 8080 and selected design we opted is to implement below.
1: Hide Release Automation Data Management Servers behind Load balancer running on Secure Port
2: Configure Load balancer over the secure port of Data Management Servers
With above configuration in place you will observe below.
Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
at sun.security.validator.PKIXValidator.doBuild(Unknown Source)
The reason for above where ASAP fail to render over SSL is because it was missing configuration require to secure UI communication.
Release Automation Version 6.1 and higher
Please follow step below.
