Common error messages in Squarespace

This guide includes a list of common error messages in Squarespace and recommended solutions.

Tip: If you see an error, check if parts of the page are highlighted. Some error messages explain how to resolve the issue.


If the error message you see isn't listed in this guide, it may be related to a system-wide issue we're fixing. Check our Status page to see if there are outages that may be affecting your site.

Browser and security

Message Next steps
403 "Forbidden" and 429 "Too many requests"

There are two reasons why this error might happen. Our servers might be blocking your IP address because we're seeing a high volume of requests, or it could be an issue with your domain's DNS settings.

To fix the issue:

  1. Visit this demo Squarespace site and complete the CAPTCHA. Usually, the block on your IP address will be removed within six hours.
  2. If the demo site doesn't display a CAPTCHA, your IP address probably isn't blocked. Go to your site's built-in domain to see if you have access.
  3. If you can access your built-in domain but not your custom domain, there's probably an issue with your DNS settings. If you use a Squarespace domain, go to your Advanced settings panel, in the Nameservers tab, click Use Squarespace nameservers, and save your changes.
  4. If you still have trouble, contact us.

Note that unblocking your IP address in step 1 isn't permanent. You may need to repeat this process again in the future.

502 Bad Gateway

There are a few reasons this error might happen. There could be something wrong with your domain, or it could just be an issue with your browser or connection.

To fix the issue:

  1. If you use a third-party domain, click Settings, and then click Domains, and check if the domain is connected. If you see a red error message, visit Troubleshooting domain connections.
  2. If you tried to visit your site using an https:// connection, ensure SSL is enabled for your site.
  3. Try opening your site from another network, as there may be a firewall blocking access to
  4. Clear your browser’s cache.
503 Service Unavailable

This error message may be related to a system-wide connectivity issue. Review our Status page to check for outages that may be affecting your site.

If there isn't a system-wide issue, follow the steps in Troubleshooting browser issues.

Blocked for security reasons

This site contains Malware

This resource has been blocked by your administrator

Unusual traffic detected

This message appears as a security measure if we detect an unusually high number of requests from the same IP address at the same time.

Sometimes a connection, hardware issue, or browser extension falsely triggers this message. In rare cases, it happens if there are many devices on the same network looking at your site.

To fix the issue:

  1. Complete the CAPTCHA field that appears. This removes your IP from our abuse filter for 12 hours and typically resolves the issue.
  2. If you see the message again after a few visits, contact us. Include your IP address in your message. If you need help finding your IP address, visit What is My IP Address.
Your connection is not fully secure

You may see this error message if you use third-party blocks or custom code to display content from other sites, which might not support SSL.

To learn more about mixed content, visit Getting started with SSL.

Your connection is not private

Your browser detected insecure content on the page, which usually means there's an issue with your SSL certificate.

To fix the issue:

  1. Ensure SSL is enabled in the Security & SSL panel.
  2. Use our troubleshooting steps to check your site for mixed content or a certificate error.
  3. If you still see the message, check for issues related to your browser.
