SSL Redirection Certbot / Too many redirects / Nginx Default page shows on Server IP

Hi,

First time writing here, Hope someone could help.

I have a domain DNS pointed as below:

A RECORD

@ pointed to SERVER_IP www pointed to SERVER_IP

I am not using CNAME as I was following tutorial on Digital Ocean. Let me know if that is the route I should go for.

Anyways, I followed all the tutorial as mentioned in Initial Ubuntu Server and Also Lemp Install. Nginx Installed, PHP working good.

Then I try to install SSL Certificate using Certbot. CertBot Tutorial finished with no errors however, My website is not having redirection error. I selected redirect all http to https since my goal is that

http://DOMAIN.tld should forward to https://www.DOMAIN.tld http://www.DOMAIN.tld should forward to https://www.DOMAIN.tld

Also note if I enter my SERVER_IP in browser it was showing nginx default page. I removed unlink default from the /sites-enabled/ I’m not sure if that is the cause of the error.

Please let me know what am I doing wrong since I’m stuck here for a long time.
