Dear Sir or Madam,
I am trying to retrieve a Twitter Card for the following URL:
However, I am facing an error: validator replies that the domain “disk.yandex.com” is not approved. Unfortunately, when I try to approve the domain I receive a message stating that the URL I provided for “disk.yandex.com” to use the summary card did not validate.
Additionally, it seems that the following preview URL does not validate (I am getting “Failed to get a proxied URL for the image” errors):
Looking forward to hearing from you.
