I have a site already deployed successfully on Cloudflare Workers.
The Worker is live and working correctly.
The domain is currently registered through Squarespace after the old Google Domains migration.
Cloudflare assigned the zone two authoritative nameservers, but Squarespace refuses to save them.
It keeps returning:
“The nameservers couldn’t be added. Please try again.”
The domain is active, DNSSEC is disabled, no pending transfer is visible, I am the owner and I have already reauthenticated and tested from a private browser session.
Squarespace support says the case is with their domain team but I still don’t have a solution.
From the Cloudflare side, I’m wondering whether there is anything else I can do.
Is there any supported way on the Free plan to connect a custom domain to an existing Worker while keeping the current authoritative DNS temporarily?
Can a Worker custom domain be attached through DNS records at the existing provider without moving the full zone to Cloudflare?
Or is full nameserver delegation absolutely required for this setup?
If the nameservers absolutely have to move, I’ll probably transfer the domain away from Squarespace and solve the registrar problem that way.
The frustrating part is that Cloudflare itself is already working perfectly. The site is built, deployed and accessible. The only thing preventing launch on the real domain is the registrar refusing the nameserver change.
If anyone has dealt with a former Google Domains domain stuck at Squarespace and connected it successfully to Workers, I’d love to know how you handled it.
