How to DNS IP refresh


I have a website - which was on an old server and the app code was old. So I updated the app code but I didn’t update the Ubuntu server - I just created a new server - which has a new IP.
Then I came to Cloudflare and under the DNS - I put the new IP for the new server.

The issue is that the website is not working anymore. I read that it might take 24h or even 72h until it starts working with the new IP?

Is there a way to ask for a DNS reindex? This is what Bard keeps telling me to hit the refresh DNS button but I don’t have something like that in my DNS section.

I am not even sure I am doing things right - is this the correct way to switch IPs?
How long will it take? I am worried about my website being down.
And can I do anything to make it reindex faster?

What is the website?

The website name is
The old IP was
New IP is

Your origin is not accepting HTTPS connections on port 443. HTTP on port 80 is working. As a result, through Cloudflare HTTP is working but HTTPS is not.
