We have two domain SSL certificates registered and in use on IIS.
e.g., *.aaa.co.kr / *.bbb.co.kr
The certificates are registered on the sites in IIS, and after checking the server name indication, everything seems to be operating fine. However, suddenly an error occurs on the site using the second certificate, stating ‘Your connection is not private’ and it seems to be mismatching the domain with the first SSL certificate.
When checking the *.bbb.co.kr site on https://www.ssllabs.com/ssltest/, it appears to be connected with the *.aaa.co.kr certificate.
The firewall also has the certificates registered, and there are no issues reported.
This issue occurs on Chrome and Edge browsers.
If anyone has encountered a similar issue and resolved it, please provide some insights.
