HTTPS + (site name here) redirects to a different site

Hello

If the account is assigned a shared IP address, and a SSL certificate is installed on that IP address, then any secure request to a domain name on that IP address will load the contents of the domain name the certificate is installed for. This is by design. You will need to assign a dedicated IP address to the account that uses the SSL certificate if you don't want that certificate applied to the other domain names on it's IP address. Or, you could generate/install a self-signed certificate for each domain name on the server (Assuming your server supports SNI).

Thank you.
