Two SSL certs does not work together

[KimBO]

Hello!

I need some support for this issue:

Cpanel runs on server.domain1.tld. A SSL cert is exposed to this domain. A reseller has bought a cert for www.domain2.tld and want to forward/redirect his customers to this URL
https://www.domain2.tld/cpanel or
https://www.domain2.tld:2083.

server.domain2.tld have not the same IP like www.domain2.tld.

But I get everytime a warning message, that the cert belongs to server.domain1.tld and be requestet from www.domain2.tld.

I tried the following things, but they also do not work:

1. When visiting /cpanel or /whm or /webmail with ssl redirect to the servers hostname.
2. Disable Http Authentication for cPanel/WebMail/WHM Logins (forces cookie authentication)

Does it works when the both domain has the same IP adresses? Do some of you have this run and could give me an advice to fix this?

THX for help!

Each SSL certificate must have it's own IP.
