linux - openVPN and myhttpd on port 433

I'm trying to set up OpenVPN to listen on port 443 on my Asustor NAS, and then pass all HTTPS traffic to Apache, by using the port-share option based on:
OpenVPN port-share with Apache/SSL

However i'm not getting it to work.
I think the problem is that port 443 seems to be listening to a process myhttp.
When i run the # netstat -tulpn | grep LISTEN command, i'll get this result:

tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 4475/myhttpd

When i change the port on OpenVPN to 444 and run the # netstat -tulpn | grep LISTEN command again, i'll get the next result:

tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 4475/myhttpd

tcp 0 0 0.0.0.0:444 0.0.0.0:* LISTEN 1507/openvpn

tcp 0 0 127.0.0.1:1195 0.0.0.0:* LISTEN 1507/openvpn

I'm not sure how to solve this issue.
Does anyone have suggestions?

Answer

The issue is that your Apache is listening to 0.0.0.0:443, when you need to set it up to listen to localhost:443. Then you won't get conflicting ports for servers.
