The official website disappeared from the Yandex search, what's the problem?

Question

Yandex

Once upon a time there was a site (loveyou.ua)
And literally yesterday it disappeared from Yandex search. More precisely, the results when you enter the address itself are displayed, but, firstly, they are far from being in the first positions (earlier when you entered the phrase "love you" it was in the first positions), and, secondly, everything is fine in Google.
Of the latest changes, only the name of the site in the header changed, but there was not a significant change.
Will it go away on its own or am I fined for something?
Thanks in advance for your help!

Answer 1

write to Plato
and remember, was it definitely in the first place, was it not a regional search
, and, thirdly, was it in the first, but did it give traffic?

Answer 2

when entering the phrase "love you" was in the first positions

What about a bedding site?
even if you return it to the first positions on this request, which I strongly doubt, I would advise you to focus on commercial requests.
