Attempting to remove a custom domain that is registered with Cloud Connector

What is the issue you’re encountering

I am trying to remove the domain a1c1.uk from R2, but I receive the error: “Attempting to remove a custom domain that is registered with Cloud Connector.” I cannot remove the binding, and it prevents me from adding an A record to point my domain to SiteGround.

What steps have you taken to resolve the issue?

  1. I checked the R2 dashboard and tried to remove the domain from “Custom Domains.”
  2. I checked Cloudflare Zero Trust, Access, Workers, and other services to see if the domain was actively used.
  3. I searched for “Cloud Connector” settings but could not find any related options in my dashboard.
  4. I attempted to edit or delete the R2 record in the DNS settings, but it is locked.

What are the steps to reproduce the issue?

  1. Go to R2 → Settings → Custom Domains.
  2. Attempt to remove the domain a1c1.uk.
  3. The error “Attempting to remove a custom domain that is registered with Cloud Connector” appears, and the action cannot proceed.
