Changed my nameservers, but Cloudflare can't detect them.

Randomly, Cloudflare removed me from my own domain, even though I didn't change a thing. I used this domain on Cloudflare for email routing and I used some emails there for accounts I now need, my domain is "tekcor.ml", if that helps. I do not know what is going on but, I've tried fixing this for the past few weeks and nothing seems to work.
