Very, Very Strange
I run a Fedora 2 machine with cPanel. Today I tried to install a ssl certificate for a friend. Everything seems to be ok but https://secure.domain.com where crt was installed, not.Extras from httpd.conf - apache 1.3.33:
<VirtualHost x.x.x.x>
ServerAlias secure.domain.com
ServerAdmin webmaster@secure.domain.com
DocumentRoot /home/secure/public_html
BytesLog domlogs/secure.domain.com-bytes_log
ServerName www.secure.domain.com
<IfModule mod_userdir.c>
Userdir disabled
Userdir enabled secure
</IfModule>
<IfModule mod_php4.c>
php_admin_value open_basedir "/home/secure:/usr/lib/php:/usr/local/lib/php:/tmp"
</IfModule>
<IfModule mod_php5.c>
php_admin_value open_basedir "/home/secure:/usr/lib/php:/usr/local/lib/php:/tmp"
</IfModule>
User secure
Group secure
TransferLog /usr/local/apache/domlogs/secure.domain.com
ScriptAlias /cgi-bin/ /home/secure/public_html/cgi-bin/
</VirtualHost>
<IfDefine SSL>
<VirtualHost x.x.x.x:443>
ServerAdmin webmaster@secure.domain.com
DocumentRoot /home/secure/public_html
ServerName secure.domain.com
UserDir public_html
User secure
Group secure
ScriptAlias /cgi-bin/ /home/secure/public_html/cgi-bin/
SSLEnable
SSLCertificateFile /usr/share/ssl/certs/secure.domain.com.crt
SSLCertificateKeyFile /usr/share/ssl/private/secure.domain.com.key
SSLLogFile /usr/local/apache/domlogs/secure.domain.com-ssl_data_log
CustomLog /usr/local/apache/domlogs/secure.domain.com-ssl_log combined
SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
</VirtualHost>
</IfDefine>
On that machine I have installed mod_security with default config in /usr/local/apache/conf/modsec.user.conf. This could affect ssl?
Also, from apf firewall config:
Common ingress (inbound) TCP ports
IG_TCP_CPORTS="21,25,53,80,110,143,443,465,953,993,995,2082,2083,2086,2087,2095,2096,3306,3000_3500,sshport"
Common egress (outbound) TCP ports
EG_TCP_CPORTS="21,25,37,53,80,110,113,#123,443,43,873,953,2089,2703,3306"
List SSL Hosts show that host as installed (btw, is the only one

What could be the problem?
Thank in advance!!!
