Redirection Problem – FORCE_SSL_ADMIN using Cloudflare SSL as a Page Rule

I am using cloudflare pro – and I added a page rule for mysite.com/wp-admin to use SSL. I browse https://mysite.com/wp-admin and it works fine. But deeper in the admin pages – it looks like it goes back to the non ssl version of the page.

So I edit my wp-config and set “FORCE_SSL_ADMIN” to true – the problem is I can’t get to the admin pages – stating a redirection problem.

Any ideas on where the problem is? Anyone having the same issue?
