   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A/AAAA record(s) for that domain
   contain(s) the right IP address.

I have no idea why this wouldnt work

Your two domains point to different IP addresses and do not serve the same content:

$ curl -i
HTTP/1.1 200 OK
Server: nginx
Date: Thu, 29 Mar 2018 20:47:10 GMT
Content-Type: text/plain
Content-Length: 45
Connection: keep-alive


$ curl -i
HTTP/1.1 404 Not Found
Server: nginx/1.10.3 (Ubuntu)
Date: Thu, 29 Mar 2018 20:47:17 GMT
Content-Type: text/html
Content-Length: 178
Connection: keep-alive

<head><title>404 Not Found</title></head>
<body bgcolor="white">
<center><h1>404 Not Found</h1></center>
<hr><center>nginx/1.10.3 (Ubuntu)</center>

Perhaps the solution is to point both domains to your nginx server, but that would be up to you to decide what is correct.
