How can I troubleshoot the issue when my Webflow site, which I have linked to a custom domain, returns a "this page isn't working" error? This is my first time publishing a site and I followed the instructions given by Webflow. Thank you!

Your Webflow site returning "this page isn't working" after connecting a custom domain usually points to an issue with domain configuration or DNS propagation.

​

1. Verify Domain Status in Webflow

​

• Go to Project Settings > Hosting in your Webflow dashboard.
• Scroll down to the Custom Domains section.
• Make sure both the root domain (example.com) and the www subdomain (www.example.com) show a green Connected status.
• If either shows Unconnected or Needs Attention, review the DNS settings associated with it.

​

2. Check DNS Records on Your Domain Registrar

​

• Log into your domain registrar (e.g., GoDaddy, Namecheap, Google Domains).
• Make sure all DNS records match Webflow’s recommendations:
• A Records for the root domain (example.com) should point to:
  • (a) 75.2.70.75
  • (b) 99.83.190.102
• CNAME Record for www.example.com should point to:
  • proxy-ssl.webflow.com
• Make sure there are no conflicting records, such as an old IP or another CNAME for the root.

​

3. Set the ‘www’ Domain as Default in Webflow

​

• Webflow recommends setting the www version as the default domain.
• In Project Settings > Hosting, click the “Make Default” button next to www.example.com.
• This ensures proper redirection from non-www to www.

​

4. Wait for DNS Propagation

​

• DNS changes can take up to 48 hours, though it's typically faster.
• Use a tool like https://dnschecker.org/ to confirm if DNS records have propagated globally.

​

5. Clear Cache and Test in Incognito

​

• Clear browser cache or open the site in an incognito/private window.
• Sometimes local caching can make it seem like the site isn’t working.

​

6. Check SSL Status

​

• Still in Hosting settings, verify that SSL is enabled.
• Webflow handles SSL automatically, but if toggled off, it can prevent secure access (https).
• Toggle it off and back on if you suspect SSL has gotten stuck.

​

7. Confirm the Site is Published

​

• In your project, click Publish and choose Both Selected Domains (Webflow.io and your custom domain).
• If you only published to the Webflow.io subdomain, the custom domain won't show anything until published explicitly.

​

Summary

​

The “this page isn’t working” error on a Webflow custom domain is typically due to incorrect DNS records, missing SSL, or failure to set the correct default domain. Double-check DNS settings, wait for propagation, publish to the custom domain, and set www as default to resolve this issue.
