Your problem has nothing to do with unbound(8). You have IPv6 misconfigured on your machine, so fix that. This also explains why you normally can resolve domains: unfortunately, IPv6 is still not that popular which means unbound normally has no choice but to communicate with the nameservers via IPv4 which you likely have set up correctly. In the meantime, set do-ip6 to no in unbound.conf(5); but don't ignore your misconfigured IPv6 setup. There are likely other issues happening that you don't know.
