Problem with bots?

Question

PHP

Hello!
At pagespeed, google refuses to check the site with a FAILED_DOCUMENT_REQUEST error.
On the Yandex webmaster site - the server's response, when requesting infoteka.pw , it cannot load the page.
Maybe something is wrong in the configs? Although, in an early version of nginx, everything worked well.
