You shoud try lsof -i tcp:443 -s TCP:LISTEN as root or netstat -tulpen |grep 443 and dont be confused, if its output only contains a IPv6 listening socket. As man ipv6 says: "IPv4 connections can be handled with the v6 API by using the v4-mapped-on-v6 address type; thus a program only needs to support this API type to support both protocols. This is handled transparently by the address handling functions in the C library. IPv4 and IPv6 share the local port space. When you get an IPv4 connection or packet to a IPv6 socket, its source address will be mapped to v6 and it will be mapped to v6." Also search for multiple "Listen" lines in your Apache conf. If nothing helps, reboot.
