Getting error on Subdomain configuration

I activated WordPress Networks using Subdomains and am not able to access any network site (only the primary is accessible – primary site & dashboard work fine).

Here is what I have done so far:

1) Added a wildcard to DNS

2) Checked to make sure my server ip is static ( )

Inspite of the above, subdomain networks are not working.

I’m on a Hostgator Linux VPS server with cPanel (if this matters at all )

Any help is much appreciated.
