Why did the Yandex.map markers disappear during the site transfer?

Question

Yandex

On one hosting there was a site with a Yandex map and tags, the site was transferred to another hosting and the amrkers flew off. It used to be like: I click on the name of the city (the button is outside the map) and the map is transferred to this place and marked with a marker. and now everything is the same but without the marker. how to return markers?

Answer 1

I assume that somewhere in the Yandex.Maps API settings you have registered the domain on which the site works. When the site was transferred, the domain changed and Yandex.Maps now does not send information to the new domain, because it is not aware of it. In short, if Moskus is wrong and you transferred all the byte to byte and still does not work, then tune in Yandex.
