Hello experts. Environment: oVirt: Software Version:4.4.10.7-1.el8 OS: CentOS Linux release 8.5.2111 Symptoms: 1. At login prompt I see this: "PKIX path validation failed: java.security.certCertPathValidatorException: validity check failed" which successfully resolved by "engine-setup --offline" 2. Now the host at 'Unassigned' status and all VMs marked with '?' symbol. At vdsm.log I found message: ERROR (Reactor thread) [ProtocolDetector.SSLHandshakeDispatcher] ssl handshake: socket error, address: ::ffff:..... (sslutils:272) At engine.log I found messages: ERROR [org.ovirt.engine.core.vdsbroker.monitoring.HostMonitoring] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-2) [] Unable to RefreshCapabilities: VDSNetworkException: VDSGenericException: VDSNetworkException: PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed ... 2024-06-10 17:54:13,576+05 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.HostMonitoring] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-8) [] Unable to RefreshCapabilities: VDSNetworkException: VDSGenericException: VDSNetworkException: PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed Cause: Certificate expired.
