We have been running a SFTP site for a while now and starting today have needed to add another site into our mix. We downloaded and follow the setup guide as recommended and we are now currently hosting both domains on a virtual machine. Since, we knew we were going to be adding this domain we added a NIC to our VM in order to allow two different IP addresses with the same port number.
However, this brings us to our issue. When using the same port number our new domain will point to our other website when we search for it on Google. For example if our existing domain is "https://olddomain.com" and our new one is "https://newdomain.com" the new domain will send us to our old domain webpage.
What could be causing this?
