If your CDN is not working properly, don’t worry — most issues are quick and easy to fix.


Check 1: Is Your Website Still Loading?

First, make sure your main website is working normally.

If your website is down, the CDN will not be able to load anything.


Check 2: Is Your Pull Zone Set Correctly?

Your Pull Zone should point to your website address.

Example:

  • https://yourdomain.com

If this is wrong, your CDN will not load your content.


Check 3: Are You Using the Correct CDN URL?

Make sure your website is using the correct CDN address:

  • Default: yourzone.b-cdn.net
  • Custom: cdn.yourdomain.com

If the wrong URL is used, files will not load.


Check 4: DNS Not Set Up Correctly (Custom Domain)

If you are using a custom domain (like cdn.yourdomain.com), check your DNS:

  • Type: CNAME
  • Points to: yourzone.b-cdn.net

DNS changes can take time to update (sometimes up to a few hours).


Check 5: SSL Not Enabled

If your site uses https://, your CDN must also have SSL enabled.

If SSL is not active, browsers may block content or show errors.


Check 6: Website Cache

Your website or browser may be showing old content.

Try:

  • Refreshing the page (Ctrl + F5)
  • Clearing your browser cache
  • Clearing your website cache (if using caching plugins)

Check 7: Mixed Content Errors

If your website uses https but loads CDN files over http, they may be blocked.

Make sure your CDN URL starts with:

https://


Check 8: Firewall or Security Blocking

Some servers or security tools may block CDN requests.

If unsure, contact support and we can check this for you.


Summary

Most CDN issues come down to:

  • Incorrect URL
  • DNS not set
  • SSL not enabled
  • Caching

If you’re still stuck, contact our support team and we’ll help you get it working.
