A DNS error on Squarespace can disrupt your website's accessibility and affect user experience. Here is a comprehensive guide to troubleshoot and fix DNS errors on your Squarespace site:

Step-by-Step Guide to Fix DNS Errors on Squarespace

1. Verify Domain Connection

First, ensure your domain is correctly connected to Squarespace. If you're using a third-party domain, check your DNS settings.

• Log In to Squarespace: Go to your Squarespace account and navigate to your website's settings.
• Select ‘Domains’: Under Settings, select “Domains.”
• Check Domain Status: Look at the connection status of your domain. If there's an error, Squarespace will likely provide a message or indicator.

2. Correct DNS Settings for Third-Party Domains

If your domain is registered with a third-party provider (e.g., GoDaddy, Namecheap), you need to ensure the DNS settings point correctly to Squarespace.

• Access DNS Settings: Log in to your domain registrar’s control panel and find the DNS or name server settings.
• Add A Records: Add the following A records (replace "204.93.213.45", etc., with the actual IPs provided by Squarespace):
• Host: @ TTL: 3600 Type: A Value: 198.185.159.144
• Host: @ TTL: 3600 Type: A Value: 198.185.159.145
• Host: @ TTL: 3600 Type: A Value: 198.49.23.144
• Host: @ TTL: 3600 Type: A Value: 198.49.23.145
• Add CNAME Record: Add the CNAME record for ‘www’.
• Host: www TTL: 3600 Type: CNAME Value: ext-cust.squarespace.com
• Save Changes: Save the changes. DNS propagation can take up to 48 hours, but often it takes a few hours.

3. Verify and Correct DNSSEC Settings (If Applicable)

DNSSEC adds a layer of security to your domain. However, if not configured correctly, it can cause DNS errors.

• Check DNSSEC Status: Go to your domain registrar’s control panel and check whether DNSSEC is enabled.
• Disable DNSSEC Temporarily: If enabled, try disabling DNSSEC and check if the DNS error on Squarespace resolves. If it does, consult with your domain registrar for proper DNSSEC configuration.

4. Clear Browser Cache and DNS Cache

Sometimes, cached data can cause DNS errors. Clear your browser and DNS cache to ensure you are viewing the most recent settings.

• Clear Browser Cache:
• Open your browser settings.
• Locate the privacy or history section.
• Clear your browsing data, ensuring that you clear cached images and files.
• Clear DNS Cache:
• On Windows, open Command Prompt and type ipconfig /flushdns.
• On MacOS, open Terminal and type sudo killall -HUP mDNSResponder.

5. Use Online DNS Checkers

Online DNS checkers can provide insights into DNS errors and propagation status.

• Use Tools like: DNSChecker.org or WhatsMyDNS.net.
• Input Your Domain: Enter your domain name to see the current DNS records and their propagation status globally.
• Identify Issues: Look for any inconsistencies or errors in DNS records.

6. Contact Squarespace Support

If the problem persists, contacting Squarespace’s support can provide more tailored assistance.

• Submit a Ticket or Live Chat: Go to the Squarespace Help Center and submit a support ticket or use live chat.
• Provide Details: Give a detailed description of the issue, including any error messages and steps you’ve already taken.

Relevant Considerations and Limitations

• DNS Propagation Time: Changes in DNS settings can take up to 48 hours to propagate fully across the internet.
• Registrar-Specific Instructions: The steps to configure DNS settings can vary by registrar, so consult their specific documentation if needed.
• Technical Support: In case of complex issues, seek assistance from your domain registrar’s or Squarespace’s technical support.

By following these steps, you should be able to diagnose and fix DNS errors on your Squarespace website. If all else fails, professional support is always available to help resolve any lingering issues.
