What I Wanted to Do

Use a domain registered on Xserver as a custom domain for a Cloudflare Pages site.

Overview

Get nameservers from Cloudflare
↓
Change nameservers on Xserver to Cloudflare
↓
Wait for Cloudflare status to become Active
↓
Activate custom domain in Cloudflare Pages

Steps

1. Connect a Domain in Cloudflare Pages

  1. “Workers & Pages” → project → “Custom domains”
  2. “Set up a custom domain” → enter your domain → “Continue”
  3. “Begin DNS transfer” → “Continue to activation”
  4. Note the two Cloudflare nameserver addresses shown

2. Change Nameservers on Xserver

  1. Log in to the Xserver domain management panel
  2. “ネームサーバー設定” → “その他のサービスで利用する”
  3. Enter the two Cloudflare nameserver addresses → Save

3. Wait for Active Status in Cloudflare

  1. Click “I updated my nameservers”
  2. Wait 30 minutes – 1 hour
  3. Once the status shows “Active”, you’re ready

4. Activate the Custom Domain

  1. “Custom domains” → enter your domain → “Continue”
  2. Click “Activate domain”

Common Pitfalls

  • Don’t try to activate the custom domain before the nameserver change is complete — it won’t proceed
  • The process requires two separate steps: first go Active, then activate the custom domain

After your domain is connected, verify HTTPS is working correctly with How to Check SSL Settings for a Custom Domain on Cloudflare.
