I have installed new ssl cert to the web server , I use third party ssl checker to find that using ipv4 to test ssl cert , it pass , while using ipv6 to test , the result shows that the ssl cert is expired .
What make such difference , what will be the cause , DNS , web server configuration or cert issue ?
On the public key of your certificate, run this openssl command against it:
Code:
openssl x509 -in <your certificate public key file> -text -noout
Review the subject, or common name attribute (can't remember which at the moment) and see if it is the fully qualified domain name of your server or an IP address. It is unlikely an IP address, unless your server is a piece of network equipment that doesn't have an fqdn.
My thoughts were that openssl didn't know what to do with an IPV6 address but that's probably not it - what is the "not after date" attribute of your certificate; is it in the future?

What are you actually sending to the server and what is the error? If you are connecting by IPv6 address instead of hostname, then you probably are missing the IPv6 address in the SAN list in your certificate.
