Why, after transferring the site to another hosting, VKontakte does not see new pages?

Question

MODX

Two days ago, the site primechaniya.ru was transferred from shared hosting to VPS.
Now VKontakte, when trying to insert a link, gives a "404 Error" from the site itself, although the page is in place and everything is in order with it. At the same time, pages added before the transfer are displayed normally in VK.

Answer 1

This is not IPV6. This is a trite VK cache that is updated within 48 hours. At the moment, the links are all loading for me, I'm waiting for a response from Pavel. On the server, no changes were made, since everything is fine there.

Answer 2

I tried to put in my primechaniya.ru/home/news/5709/5742
everything opens.
Is this an attempt to get perpetual links?

Answer 3

Faced the same problem. Set up IPv6 on the new hosting.
