[ovirt-users] Ovirt version 4.4.9.5-1.el8 getting error PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Hi All, I just have installed a Ovirt host using all the default settings from the manual. I started with a CentOS 8 minimum install Then I followed the Ovirt installation guide to install Ovirt version 4.4.9.5-1.el8 Now I try to log on to the Administration portal and I get the following message : PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target When searching the internet then I get several answers but all about using certificates from third-parties. I don’t use third-party certificates. When I look in the OVIRT administration guide they only talk about third party certificates So can anyone help to fix this error?
