This article will show you how to fix the Webflow error that states that "You'll need to remove the AAAA record from your DNS settings to ensure your site loads properly."
You will likely encounter this problem when trying to point a custom domain to your Webflow website. If you're positive that this record does not exist in your DNS, there's a quick and easy fix. This error is occurring because you are proxying all your traffic through Cloudflare - by default, if you use this service for your website it is said to do this. There are numerous benefits they Cloudflare has to offer such as DDOS protection, but you cannot be tunneling traffic through the service if you want to use your domain with Webflow.
The good news is that you can still use Cloudflare to manage your DNS, and all you need to do is turn the proxy status to DNS only. This will allow Webflow to completely access the domain name, provision an SSL certificate, and remove the error message of "You'll need to remove the AAAA record from your DNS settings to ensure your site loads properly."
In this example, you can see that we have set our WWW CNAME to the Webflow SSL proxy, and turned the Cloudflare proxy status to DNS only.
Even if you don't see it, when traffic is proxied through Cloudflare, an AAAA record is added - so this error message is an incorrect, but it is a bit difficult to determine the cause of it when using Cloudflare as you simply cannot see that an AAAA record exists. - you can check here: https://dnschecker.org/#AAAA
