Hello, is Apache 2.2 which is part of the CentOS distribution capable of SNI? I have troubles that are coming from server side (CentOS 6.8, Apache 2.2.15) just did 'yum update' in /etc/httpd/conf/httpd.conf I've the following NameVirtualHost ipaddr:443 Include /etc/httpd/conf/vhosts/vhost-ssldom1-box.conf Include /etc/httpd/conf/vhosts/vhost-ssldom2-box.conf both 'vhost'-files are like this: <VirtualHost ipaddr:443> ServerAdmin webmaster at domain#.com ServerName vhost.domain#.com:443 ServerAlias box.domain#.com:443 ServerAlias calcbox.domain#.com:443 ServerAlias proxybox.domain#.com:443 ... SSLEngine on SSLStrictSNIVHostCheck on SSLCertificateFile /etc/httpd/conf/ssl.crt/domain#-host.crt SSLCertificateKeyFile /etc/httpd/conf/ssl.key/domain#-host.key SSLCertificateChainFile /etc/httpd/conf/ssl.crt/server-chain.crt ... </VirtualHost> only https://domain1.com/... works https://domain2.com/... results in a certificate CN mismatch ... what is missing in my config.? Thanks, Walter
