WordPress set up on Droplet (Digital Ocean)

Hello, I am setting up my wordpress site. My domain was purchased on njal.la and I want to set up the wp site on a droplet on digital ocean, then set up the cdn on cloudflare.
I have set up a project under in my account with the droplet. I have changed the name servers from njal.la and pointed the domain to cloudflare. Then I set up the virtual machine with wp on the droplet. Using the IP address generated from the project I added an ‘A record’ in cloudflare. Then I went into my wordpress site and changed the site name from the IP address to my domain.

Can you confirm if this is correctly set up? It has been about 36 hrs, the url for my wp-admin has not changed from the IP address to the domain name. I was also previously able to access the wp-admin but not i’m not able to. Can you confirm if I set it up correctly?
