Why after changing the hosting Yandex "Checking server response" refers to the old hosting?

Moved WP site to new hosting, everything works fine. But, Checking the server response in Yandex Webmaster issues a 403 error and ip of the old host. How to fix it? Gone are the nights since moving in.

Solution
The problem was solved, Yandex took about ~40 hours to update the data.
In fact, almost everywhere write, that DNS update may take up to 48 hours. So wait at least 3 days before asking your question. Because it is caused by a misunderstanding on your part, it would be better to remove it so as not to stumble on him in vain in search results. - meta_Abernathy commented on March 19th 20 at 09:10

Maybe just old hosting already closed? For example, for non-payment. Or the old hosting is in Ukraine where access to Yandex closed(almost) and according to this, the Yandex webmaster gives a 403 instead of 200.

Check whether the domain redirected to the new hosting.
