In the event of an unsuccessful VAT validation, it's possible that the VIES (VAT Information Exchange System) is temporarily unavailable. The VIES is the system used by the European Commission for validating VAT numbers. If you are confident that your VAT information is accurate, you have the following options:
1. Proceed with registration without including your VAT number. You can add your VAT number later through the dashboard in your account settings.
2. Attempt the VAT validation process again.
