When checking the links https://1cert.ru/stati/vy-pank-kachestva/amp in the service for validity https://search.google.com/test/amp, everything is fine.
Link to the test I am enclosing https://search.google.com/test/amp?id=cVC11sfekmofU927klDf5A.

When checking the link https://1cert.ru/stati/vy-pank-kachestva/amp for validation on the https://validator.ampproject.org/ service, the first 0.1 second slips through the error, but then everything is fine. At the same time, I believe that the problems are not in it, because https://www.bbc.com/russian/amp/features-41028204 and https://m.lenta.ru/news/2017/08/23/offshore/amp/ give out the same error at 0.1 second.

Hi @mihalzasse,

I just checked your site and the link which you have shared and it is working fine with AMP.

I even checked this on mobile and the AMP page is working perfectly fine in mobile as well.

Are you sure that you are still facing this issue?

I greet you. @marqas

Yes, as for two days, many of the AMP pages began to be indexed again.

I have an assumption that the problem was on Google servers.

But they are not in a hurry with the answer.
