Background: I have a VPS where i launched multiple websites. I then had a requirement to create a new website that will utilize the Wordpress Multisite functionality

I created my wordpress website first, and then as the requirement came, i changed it to multisite.

My Problem:

When i create a sub-domain site and want to view the website, i get redirected to the apache 2 default page. When i want to access the dashboard of sub-domain site i get redirected to another website that is on the shared vps.

Does anyone know why the multisite is loading the wrong website dashboard and showing me the apache default page when i try to visit the new website ?
