The problem arises in facebook.
Open graph image disappears within a few days for some site links (for example: https://maroom.ru/blog/19/Chem-ploha-vysokaja-stoimost). When the link is published, the image appears, but then it disappears. While other links of the same site do not have such a problem (for example https://maroom.ru/blog/7/Houm-stejdzhing )
