Can anyone provide technical help with Efty custom domain config

[Ria]

I'm trying to set up my marketplace on Efty and hit a snag with the "custom domain" feature. The instructions say

1. Log in to the registrar where your domain is hosted
2. Make sure you are using your registrars default name servers
3. Point the A-record of your custom domain to 5.153.42.104
4. Enter your custom domain below
5. Hit 'Test domain', and 'Save' afterwards
6. You're good to go!

(btw, there is no "Test domain" to hit? Just "Save")

But I think that I've not set up my DNS records (on Namecheap) properly, because it is not working. And yes, I've waited for it to propagate. This is what I have:

I am using the Namecheap default name servers (Namecheap BasicDNS)

These are Namecheap default configurations
Type: CNAME Record
Host: www
Value: parking (dot) namecheap (dot) com.

Type: URL Redirect Record
Host: @
Value: http : // www (dot) mycustomdomain (dot) com/

And I added this A Record according to the Efty instructions:

Type:A Record
Host: @
Value: 5.153.42.104

However, Efty doesn't give too many details or instructions, other than to "Point it" so I'm unsure what the Host value should be? Also, should I change and/or delete the other records? What am I doing wrong here?

Any help greatly appreciated!
