Verify your DNS configuration

• Ensure your domain points to the correct Scaleway Web Hosting IP.
• Use Scaleway’s recommended nameservers and DNS settings.
• Double-check that your A, CNAME, and MX records are properly set.
• Refer to Scaleway’s DNS Configuration Guide for details.

Check for conflicting DNS settings

• Ensure no conflicting records exist (e.g., multiple A or CNAME records pointing to different servers).
• Remove outdated or incorrect entries.

Allow time for DNS propagation

• DNS changes can take up to 48 hours to propagate globally.
• Check propagation status using tools like DNSChecker.

Clear DNS cache

• On your local machine, flush the DNS cache:
  • Windows: Run ipconfig /flushdns in Command Prompt.
  • macOS: Run sudo dscacheutil -flushcache and sudo killall -HUP mDNSResponder in Terminal.
  • Linux: Restart the DNS service or use sudo systemd-resolve --flush-caches.
• Restart your browser or try using a different network.

Test local DNS resolution

Use the nslookup or dig command to check domain resolution.

• Example:

  nslookup yourdomain.com
  dig yourdomain.com +short
  

If incorrect records appear, wait for propagation or reconfigure your DNS settings.
