Go to Currently column. If the response code differs from 200 OK, check whether the problem is current using Server response check.in Yandex.Webmaster and see what response code the page returned to the Yandex robot's requests in the
When checking the server response, pay attention to the Page content section. If the message “Missing page content” is displayed, check your server settings:
- HTTP header. For example, if it contains "Content-length: 0", the robot will fail to index the page.
- The size of the page content. It must be greater than 0 and match the HTTP header.
After you make changes, wait until the robot crawls the site again. You can also send the page for reindexing and the robot will recrawl it within two weeks.

Failed to connect to the server due to DNS error
Once a day, the indexing robot accesses DNS servers to determine the IP address of the server where the site is located. If DNS records are incorrectly configured on the site, the robot does not get the IP address of the site. As a result, the site cannot be indexed and added to search results.
Check the correctness of the server response to the indexing robot. If the site is still unavailable, contact your hosting provider to correct your domain's DNS records. When access to the site appears, information in Yandex.Webmaster will be updated within a few days.
The problem with accessing the site may be short-term. If you do not find any errors when re-checking the server response, wait for the information to be updated in Yandex.Webmaster. This should happen within a few days.
If the domain name was not renewed in time, the site becomes unavailable for indexing. Renew the domain registration. After this, the message in Yandex.Webmaster will disappear within a few days.
Site indexing is disallowed in the robots.txt file
The indexing robot requests the robots.txt file several times a day and updates information about it in its database. If the robot receives a prohibiting directive in response to a request, a warning appears in Yandex.Webmaster.
Check the robots.txt file contents. If the prohibiting directive is still present, delete it from the file. If you can't do this yourself, contact your hosting provider or domain name registrar. After the directive is removed, the data in Yandex.Webmaster is updated within a few days.
If the domain name was not renewed in time, the robots.txt file will contain prohibiting directives for the robot. Renew the domain registration. After this, the message in Yandex.Webmaster will disappear within a few days.
