sub domains IP problem

Question

Hi there

I have a VPS server and I have cPanel and WHM  installed on the server. I have a main domain mymaindom.com on which I use an SSL EV certificate. This domain has its own dedicated IP. The problem is that now my subdomains are all showing a cPanel error:default website page, indicating that the IP is wrong. The subdomains have different IPs than the main domain IP. I tried changing the main IP but that didn’t work.
Any suggestions are highly appreciated.
Many thanks in advanced

This should help, it explains how to assign dedicated IPs to subdomains

make sure that your DNS records  are matching your IP addresses configured for your server
