UPD
Hello. Who can help with solving problem 522? WP sites. Troublshouting in cloudflare say that everything should work. The hosting said that they have no problems.
Hosting: We made a selective trace from the Cloudflare IP list. As you can see, the traffic leaves our servers and the data center, on one of the test IPs it is clear that there is an obstruction of traffic packets, but this is far beyond the network of the country where the server is located.
But the Google bot cannot gain access and receives 522, the pages remain without an index and the robots.txt file is also not readable only manualy after 2-3 attempts.
Free plan. Everything worked for more than a month without problems. On December 12, these errors began to appear on 4 sites that are located in different cloudflare accounts. I did not change the cloudflare settings. On some sites, even the pages were not edited, much less plugins were installed.
