Fix common DNS records issues by following these troubleshooting steps:

Records Not Saving

Replace placeholder values in the [Host] and [Data] fields with actual values. Gray placeholder text serves only as format examples. The [Priority] field remains optional.

Host Field Format Guidelines:

  • For "mail.yourdomain.com", enter only "mail" as the system automatically adds the domain
  • Use "@" when the full domain is required without prefix
  • Avoid duplicate host values across different record types

Common Error Messages and Solutions:

Invalid IP or Hostname Error

  • Verify [Data] field format
  • Remove any trailing periods
  • Double-check value accuracy

Conflicting Records Error

  1. Open Domain Dashboard
  2. Select domain name
  3. Navigate to DNS Settings
  4. Review Custom Records
  5. Remove conflicting records
  6. Add new record
  7. Allow 24-72 hours for propagation

Priority Field Limitations

  • Only editable for MX or SRV records
  • Appears but remains inactive for other record types

AAAA Record IPv6 Format

  • Use expanded IPv6 address format
  • Example:
    • Invalid (shortened): 2620:12a:8000::3
    • Valid (expanded): 2620:12a:8000:0:0:0:0:3

TXT and DMARC Records

  • 255-character limit per string
  • Split longer records into multiple strings
  • Use online DNS record splitting tools
  • Add each string separately

Invalid Alias Data Error

  1. Ensure record is under 255 characters
  2. Remove extra characters or periods
  3. Check for typos
  4. Split long records if necessary

Support Limitations

  • Platform support covers DNS settings navigation
  • Contact third-party services for specific technical guidance
  • Use peer support forums for additional help

Remember to allow 24-72 hours for DNS changes to propagate fully across the internet.
