What is the process to add sub domain with Cloudflare and Cyberpanel whose domain name is used as custom domain name for WP multisite?

General

The domain example.Org is custom domain name that points to WP Multisite enabled example.Com WP Mu site example.Com is working fine.

/home/example.Com/

This WPMU example.Com is added via CyberPanel

I need to create a subdomain name like this ok.example.Org that uses different php-CMS (not the WP )

I’m stuck at the process …

  • Cloudflare > DNS > add A record points to server IP / @
  • CyberPanel > Create new website > do.example.Org (example.Org points to WPMU .Com site) http check result shows
  • 302
  • Connection Closed

Alright, here’s a simple, step-by-step way to get your subdomain (like ok.example.org) working with a different PHP CMS on your server using CyberPanel and Cloudflare, given your current setup:

Your Setup Recap:

  • example.org is a custom domain pointing to a WordPress Multisite on example.com
  • example.com is hosted on CyberPanel
  • You want to add ok.example.org subdomain running a different PHP CMS
  • Cloudflare is your DNS manager
  • You added the domain and subdomain, but get 302 / Connection Closed errors

Step 1: Cloudflare DNS setup

  • Go to Cloudflare Dashboard > DNS tab for example.org
  • Add a new A record:
    • Name: ok
    • Content: Your server IP address
    • Proxy status: DNS only (click the orange cloud to turn it grey). This avoids Cloudflare proxy messing with your site during setup.
  • If you already have example.org A record, no need to change it.

Step 2: CyberPanel - Add website for subdomain

  • Log into CyberPanel
  • Go to Websites > Create Website
  • In the domain field, enter: ok.example.org
  • Fill other details as needed (PHP version, owner, etc.)
  • Click Create Website

Step 3: Upload your PHP CMS files to this site

  • Using FTP or File Manager, upload your PHP CMS into:
/home/ok.example.org/public_html/

(or wherever CyberPanel created the document root)

Step 4: Check PHP & web server settings

  • CyberPanel should automatically configure the virtual host for ok.example.org
  • Make sure .htaccess or nginx config is not redirecting
  • PHP should be enabled for this site (check PHP version in CyberPanel > Websites > List Websites)

Step 5: Test your site without Cloudflare proxy first

  • Wait a few minutes for DNS to propagate (or flush your DNS cache)
  • Visit http://ok.example.org (use http first)
  • If it works, great!
  • If not, test with curl or ping to confirm DNS resolution

Step 6: If everything works, enable Cloudflare proxy

  • Go back to Cloudflare DNS and click the grey cloud next to ok record to enable proxy (orange cloud)
  • This allows Cloudflare features like SSL, caching, etc.

Troubleshooting Tips:

  • 302 redirect often means webserver or CMS is redirecting you—check .htaccess, CMS config files
  • Connection Closed means server or firewall might be blocking, or web server config is wrong
  • Check CyberPanel logs in:
/usr/local/lsws/logs/error.log

or respective nginx/apache logs for clues.

  • Make sure SSL is configured if you want HTTPS (can use CyberPanel’s AutoSSL)

Summary (Your minimal checklist)

Step What to do
Cloudflare DNS Add ok A record → IP, DNS only
CyberPanel Create website → ok.example.org
Upload CMS Upload to /home/ok.example.org/public_html
Test site Visit http://ok.example.org
Enable Cloudflare proxy Switch DNS record to proxied
