@WebpageBot - Wordpress cache reset?

Question

caching

Good day, I've been suffering all day! I can’t understand why telegram doesn’t see the description of the main page of my site. Meta tags are all correct. I am using Wordpress with the Yoast SEO plugin. If I copy a post, the page via telegram is displayed normally with a description and a picture. But when I stupidly send site.ru, it is displayed in a telegram as a stupid link without a description, pictures, etc.
I update the cache via @WebpageBot - it's useless.
Guru, tell me ...
