What's keeping iva1.dev from an A

  1. Add IPv6 for www.iva1.dev
    www.iva1.dev has no AAAA record. Get www's IPv6 address from whoever hosts www and add it as an AAAA record. If the same server already serves both names (and its certificate covers www), you can reuse iva1.dev's AAAA record(s) for www. How to add an AAAA record
