I cannot generate my digital certificate pass, I am receiving an error. Why?

Our service was developed for EU Covid Certificates (formerly called Digital Green Certificate), which should have been launched within the EU during summer 2021. Some member states have already implemented them, and you are automatically receiving an EU Covid Certificate, however in other countries it’s still in progress, or you may receive them on request at local authorities. Please note that local QR codes have different tech specifications and are not eligible for generating our digital certificate passes.
