Writes that there is no Internet, although it is. Why is that?

Question

Android

Hello!
Recently, I started to notice that some applications tell me that I do not have the Internet, although I have it turned on, and all other applications that require the Internet work.
Only VK and Yandex Toloka are like that for me. I'm from Ukraine. Tried VPN but same result.
Can you please tell me what to do.

Answer 1

So in Ukraine, Yandex, in my opinion, was blocked, no?
