[ovirt-users] HELP ME! Failed to validate the SSL certificate for localhost:443

Hi, I'm having an issue with Failed to validate the SSL certificate for localhost:443 during Deploy "hosted-engine." check the log files, found this error: " [TASK] [ovirt.engine-setup: Check if Engine health page is up] [ERROR] fatal:[localhost -> my_fqdn.domain]:FAILED!=>{"attempts":12, "changed":false,"msg":"Failed to validate the SSL certificate for localhost:443. Make sure your managed systems have a valid CA certificate installed. You can use validate_certs=False if you do not need to confirm the servers identity but this is unsafe and not recommended. Paths checked for this patform: /etc/ssl/certs, /etc/pki/ca-trust/extracted/pem, /etc/pki/tls/certs, /usr/share/ca-certificates/cacert.org, /etc/ansible. The exception msg was: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:618).", "status": -1, "url": "http://localhost/ovirt-engine/services/health"} " NOTE: ovirt engine VERSION "ovirt-engine-appliance-4.3-20200603.1.0.2.el7.x86_64" We tried googling to resolve this issue but, unfortunately, unsuccessfully. Can someone help us to solve our critical issue? Best regards, Bunnatee
