The site does not want to be indexed. The same problem was on old hosting ultimatefreehost.in
The official Google support forum says this is a server problem. Google does not see the site. You need to look at the server logs.
I did not find any in the server log folder.
Help solve the problem.
How can I see server logs?
Even if the security system is not a problem for some bots and crawlers, because these may have JavaScript and cookies enabled and can access the website and index it without any problem.
It’s possible that the bot protection system prevents webmasters tools from fetching the robots.txt file. We know that the Google site crawler can access websites on free hosting, but it’s possible the webmasters tools do not actually use the site crawler to fetch the robots.txt file.
In fact, if you type site:hudozhnik-restavrator.ru in Google, you’ll see many pages of your website have been indexed just fine. So I guess the webmasters error is a false positive?
Got a response from Google expert
“Most likely the problem of network accessibility, or the firewall / antidos settings are blocking the exchange. Your hosting should know about these settings.”
I just checked hudozhnik-restavrator.ru through PageSpeed Insights and it’s redirecting to suspendeddomain.org. Did you remove the domain name from your account by any chance? If so, please add it again, or it will not be accessible (and so cannot be indexed).
