Cloudflare CDN is not setting up

Hi,
I had added Cloudflare CDNS to my website https://japaneseknivesblog.com/ and first, the CDNS successfully created and after few months Cloudflare is detached from my site.
So do I need to add Cloudflare again on my site?
Will it have any effect on my website?

Looks like you’re using Cloudflare, what’s the issue exactly?
