Hello! I have two problems. Not sure if these problems are related. First is strange situation with SNI and Comodo PositiveSSL certificates. I managed to configure one https site with Comodo certificate and It's working, but other two are not working. They get wrong certificate - servers and not their own. Error: SSL_ERROR_BAD_CERT_DOMAIN. Actually they don't have <VirtualHost *:443> section on sites-enabled vhost file at all. SNI is enabled on Control Panel and SSL for sites is active. I followed Ispconfig manual when adding certificates (Create cert and then change SSL cert and boundle. Save certificate). Other problem is that apache don't start after changing to Comodo signed certificate for Ispconfig Control panel on port 8080. Changed successfully with self-signed certificate (000-ispconfig.vhost). But with Comodo wild cert is not working (I can use this cert for more then one site with SNI, right?). For SSLCACertificateFile I used boundle from Comodo mail attachment. # SSL Configuration http error_log: System info: ISPConfig version is 3.1.1p1 centos-release-7-2.1511.el7.centos.2.10.x86_64 Apache/2.4.6 (CentOS) Probably something is misconfigured. I'm looking forward to read your advices and suggestions.
