Cloudflare not active?!

Hello, some days the test tells me that cloudflare is not active. But I cloudflare active! What could be the problem. How can I check if cloudflare is working?

This is my result: https://www.webpagetest.org/result/170216_YD_N2M/

Thanks.

I solved by deleting the site from cloudflare and inserting it again.
