How do I connect an existing domain?
Go to the Domains tab, click Add Domain under the “Connect an existing domain” section, then enter your domain name.
What are DNS records? Where/How do I add them?
You purchase your domain at a domain registrar (like GoDaddy, or Name.com). You build and host your app with Hercules. You use DNS records to connect your domain to Hercules so the internet knows where to find your website. You must set up your DNS records following the instructions we give you:| Type | Name | Value |
|---|---|---|
| A | @ | 104.18.220.38 |
| CNAME | www | cname.onhercules.app |
| CNAME | _acme-challenge | <your-unique-acme-challenge-value> |
| TXT | _cf-custom-hostname | <your-unique-custom-hostname-value> |
Will this work for www too?
Yes. When setting up your domain, you can choose to have all subdomains redirect to your root domain (e.g. www.myapp.com would redirect to myapp.com).

This is usually a DNS caching issue. Try clearing your browser cache, flushing your DNS cache,
or waiting a few hours. Different ISPs and devices cache DNS records for different amounts of
time.
I'm getting a Cloudflare 1016 error
I'm getting a Cloudflare 1016 error
This error happens when your domain is connected to Hercules and also has a Cloudflare Zone set
up. It usually affects the
www. subdomain, not the root domain. For example, if abc.com
works but www.abc.com shows a 1016 error, you probably have a Cloudflare Zone for abc.com.
To fix this, either remove the Cloudflare Zone for abc.com or don’t set up the www. redirect
