Changing DNS to New Server

[cvassios]

I have a domain pointing to Cloudflare’s name servers and a new website on AWS ready to replace the existing one. I have gone into Cloudflare and changed the A record to the IP address of my EC2 instance, but getting a 521 error on when I try to visit the website. Did I miss something?

Am I supposed to do anything with the name servers on Route 53? Do I create NS records in Cloudflare for the one’s provided in my Route 53 Hosted Zone? I have read a few articles and they all say to do something different in that regard.

Not sure if I’m just not waiting long enough for propagation or if I did something wrong/missed something.

Moving your site to a new host

What do I need to do at Cloudflare if I change my web host? If you change the provider hosting your website, most of the work will need to be done there. You will need to add everything to your new host. Once this is done, however, you will need to update your DNS records in Cloudflare to point to your new host. To do this, you will need to find out what DNS records you need from your new host. These will often appear in a DNS section of your control panel. If they don’t, you will need to con…

If you are using Cloudflare DNS, why do you have nameservers running on Route 53?

They were there from a previous setup for a dev environment and I just copied what I did there for the live environment.

Did you configure the domain on your EC2 instance?

@Laudian

configure the domain on your EC2 instance

If you mean associate an IP address to it, yes.

I took that question to be asking if your EC2 instance knows that it should respond to requests for that hostname.

I thought that is what Route 53 was for? Where else do I define that in the EC2 instance?

Are you using Apache as your webserver in your EC2 instance?

In that case, you need to set the hostname in your site-config and also provide an SSL certificate for that name.

Route 53 is a DNS provider not unlike Cloudflare DNS. That’s is why I asked why you are creating records in Route 53 if your authoritative DNS is configured as Cloudflare at your registrar.

I don’t know the specific answer to your EC2 question. Are you running a webserver on your EC2 instance? Does it have configuration settings available? I would start there.
