Domain name stopped resolving to VPS

I have DO VPS running on Cent OS 7. I installed nginx and Virtual min. I am not able to resolve my domain to the VPS. I have created a A record pointing to my Floating IP(static IP) in cloudflare and a CNAME www with a value @. I used the same settings before, it was working. I destroyed my droplet and built a new on but I have assigned the same static IP to the VPS. I have allowed ports 80,443 and 10000.

I have configured my nginx.conf to listen on port 443 too. But still it my domain name does not resolve to my VPS. Here is my nginx.conf

I tried checking if the ports are listening using netstat -an | grep 443 | grep -i listen and they seem to be listening. Here is my output

tcp        0      0 174.138.xxx.x:443       0.0.0.0:*                     LISTEN
