I'm at my wits' end with this.
I'm trying to do something simple, that is direct a domain (something.org) rented at Google Domains to a site made in Google Sites. I am an Owner of both the domain and the site, and we use G Suite/Google Workspace. I am an Admin in said Workspace.
Supposedly, all I had to do was go to Google Domains, click on something.org, "Build website", then follow the steps to use Google Sites, "Use Existing Site." However, doing that gets me a cryptic error message saying
This site and domain require a Google Workspace admin to make the connection manually in the admin console.
After reading through many tutorials that kept telling me to do the above, I eventually land at the Google Workspace Admin site, and try to add a Custom URL there. Except on step #3, I only have my organization's domain available to choose from (organization.org), I don't have something.org available.
If I go to Webmaster Central, I get a list of the 20-odd domains we have registered, and they all say that they're automatically verified.
In Google Sites, if I go to the site Settings, I don't have the "Custom URL" option available at all.
Alternatively, I tried setting up the DNS manually, but the problem is that in Google Sites I tried to site "something.org", only to be told that I can only use letters, numbers and dashes.
I've already read some 30 different tutorials and even videos, and I can't understand why none of this is working. Help! :)
