That log says you used the option --dns dns_yandex which would be the old plugin, not the new one using the yandex360 plugin.
@Neilpang Can you confirm that the value provided by the --dns option uses the file name of that value? I didn't find anything resembling like that file foobar.sh could provide a plugin for --dns baz for example. The correct value for the --dns option for the file foobar.sh in the dnsapi directory would be --dns foobar, right?
I can't figure out how to get a new token and which one should I get? This is what I was advised on a github anyway:
Yandex DNS API name has been changed. The new value for the --dns argument must now be set as dns_yandex360.
You must issue a new token for the updated Yandex API. Please refer to this guide for more information:Доступ к API - 360 API. api360
and you also advised to fix the DNS API Test
