Need for a network admin

Server configuration issue where network is running 2 different domains on 2 different servers on xampp. Domains are blueicetrading.capital and schon-Cleaning.com; domain blueicetrading.capital is throwing an error message where its security certificate is from schon-cleaning.com while it has its own ssl. This may be caused by a network misconfiguration. This problem needs to be solved. The 2 domains are in 2 different servers running xampp on the same network.
