Why is there no access to the classmates resource?

Question

Classmates

Greetings.
I connect yastatic.net/share2/share.js
I draw the output class="ya-share2" data-services="odnoklassniki"
as a result I get the message "No access to the resource Please try later", with the rest of the social. networks are great. (I also tried other services: pluso, yandex share - the same thing)
I also used okapi initially.
I tried and through the OExchange protocol
(site on https) I
saw a similar question on the toaster, but it did not help.

Answer 1

You should contact the author of the widget used.
From what is supported by OK:
1) sharing through the Class button! https://apiok.ru/ext/like
2) OExchange protocol https://connect.ok.ru/offer?url=http://mysite.com
