Der Domänenname lässt sich nicht in VPS auflösen

Question

Ich habe DO VPS unter Cent OS 7 laufen. Ich habe nginx und Virtual min installiert. Ich kann meine Domain nicht auf den VPS auflösen. Ich habe einen A-Eintrag erstellt, der auf meine Floating IP (statische IP) in Cloudflare verweist, und einen CNAME www mit dem Wert @. Ich habe vorher dieselben Einstellungen verwendet, es hat funktioniert. Ich habe mein Droplet zerstört und es erneut erstellt, aber ich habe dem VPS dieselbe statische IP zugewiesen. Ich habe die Ports 80,443 und 10000 zugelassen.

Ich habe meine nginx.conf so konfiguriert, dass sie auch auf Port 443 lauscht. Aber trotzdem wird mein Domänenname nicht auf meinen VPS aufgelöst. Hier ist meine nginx.conf

Ich habe versucht zu prüfen, ob die Ports mit netstat -an | grep 443 | grep -i listen lauschen, und sie scheinen zu lauschen. Hier ist meine Ausgabe

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

Es gab einige doppelte Einträge sowie falsch konfigurierte Einträge. Hier ist der aktualisierte Code:
