If you use *.example.com/* you would have to come from either www.example.com or another subdomain, but this won't work if you are coming from example.com (notice the period in the first part of the URL)

If you have some sort of redirect to example.com that strips out the first part of the URL, the best regex to use in this case is simply *example.com/* that would cover all subdomains behind example.com, http or https and all contexts after your domain.

I was able to solve the issue by simply setting the referrer to:

example.com
