Yandex Webmaster redirect to https and mirror in ru zone?

Question

Yandex

Hello!
I ran into a problem, help me figure it out ..
There is a domain, for example site.com works on the https protocol, redirecting to https is implemented from http . There are several languages ​​on the site, the link to index.php is built in this way site.com/ru or site.com/en , respectively, the domain does not work in its pure form, only with the default language RU, hence another redirect from site.com to site.com/en . A domain was also created in the RU zone site.ru, which by default refers to site.com/ru - redirection.

Everything seems to work, the site pages are indexed, at the main address https:// site.com/ru - Yandex Webmaster does not make any comments, but the following picture is very confusing. See Attachment.

Tell me why the number of downloaded pages using the http protocol is growing?
Yandex also makes comments on http:

1. robots.txt file not found
   
2. Host directive not set in robots.txt file
   

Tell me how to solve this situation correctly, in my case, does the site suffer from redirects or is this a normal situation?

Answer 1

Is this why Yandex and 301 redirects are not friends?
