Question Error initial connection

[renkeles]

Every minute this error comes out with the same IP. I don't know the IP. I blocked it via iptables and ufw. How to solve this problem? It does not depend on plugins - I checked with them and without them.

Yes, that wasn't any plugin. Except you installed Russian plugins on your machine. Because that is someone from RU (Russia)
(i hope you can do the whois command)
