Solution:
- Check DNS records: Go to Zone Editor and verify your domain's DNS settings (A records, CNAME, etc.).
- Clear local DNS cache: Flush the DNS cache on your machine or contact your ISP to clear it.
- Verify DNS propagation: DNS changes may take up to 48 hours to propagate. Use online tools to verify if the DNS settings have been fully updated.
- Check for DNS misconfigurations: Ensure your domain points to the correct server IP and your MX records are set up properly for email.
