Mistakly deleted domain from blogger but now it's can't work

I have deleted by mistake domain from blogger but now it is not asking for DNS and submitted success but can’t work my site.

I suggest you use the “Pause Cloudflare on Site” option from the Overview tab for your domain at dash.cloudflare.com. The link is in the lower right corner of that page. Give it five minutes to take effect, then make sure site is working as expected with HTTPS. Only then should you un-pause Cloudflare and double-check your SSL/TLS setting to make sure it’s Full (Strict).

I have also delete it form cloudflare now again add.
But when on blogger adding domain it is not showing DNS directly save but can’t work.
