If users with IE8 go directly to www.xyz.com, SSL cert is fine. Users going directly to www.zyx.com have no issues with cert. If users start at one site and go to the other, they get invalid cert with xyz being used on zyx which should not be happening.
Reading the forums NGINX has SNI enabled and I have the correct version of OpenSSL to be able to handle multiple certs.
IE8 seems to be the issue but these are customer facing sites. Is there a fix to make NGINX work for the customers experiencing the issue.
