CirrusProblem applying 2 EC certs to a VS - NET::ERR_CERT_COMMON_NAME_INVALID
We have a virtual server that is currently configured for SSL Offloading using an L1F EC cert by Entrust. Current cert has about 240 SANs. Customer wants to add few more SANs. To manage it efficientl...
About common name field, it was suggestion. According to link below in 14.1.4 version it isn't necessary. F5 matches SNI with SAN list.
Unfortunately, I don't have any more ideas how to solve it. Looks like a bug and reason to open a support case.

"For Server Name, enter the name of the HTTPS site.
Note: Beginning in BIG-IP 11.6.0, if you leave Server Name blank, the BIG-IP system reads the Subject Alternative Name (SAN) from the certificate. For versions prior to BIG-IP 11.6.0, if you leave Server Name blank, the BIG-IP system reads the Common Name (CN) from the certificate. Additionally, the Server Name setting supports wildcard strings containing the asterisk (*) character. For example, *.domain.com matches a.domain.com or a.bc.domain.com, but it does not match domain.com)."

CirrusWhat software version do you use?
Could you try to fill in Server Name field in srv404s_services_Board-IT-Compliant-ExtraSANs profile with hostname?
And just to be on the safe side, change srv404s_services_Board-IT-Compliant-ExtraSANs profile option defaults-from to equite.com, to make it almost similar with profile client-ssl srv404s_services_Board-IT-Compliant

Thanks for pointing that out. We are counting on relying on SANs to pick up the cert. Otherwise, we are talking about dozens of SANs in 2nd cert alone.
