Troubleshooting

License verification failed

Common causes:

  • Expired license: Renew your CT IDX Pro+ subscription
  • Wrong website URL: Ensure the URL matches your license
  • Invalid license key: Double-check the key from your account
  • Revoked access: Contact CT IDX Pro+ support

No results returned

If searches return no results:

  • Verify your MLS ID matches what we provided
  • Check that the MLS has active listings in the searched area
  • Try a broader search with fewer filters

API errors

If you see API errors, verify your API key is correct and your account is in good standing with CT IDX Pro+.
