As of yesterday, somewhere before 3 pm, I cannot access my site, for which I am the administrator and editor. I also tried it via a mobile phone that connects wirelessly to the router. It means that most likely my IP address was blacklisted, but my friend checked that my IP address was not blacklisted, and also since we use wordpress for the site, so we activated the wordfence security plugin, my IP address was not found there either. Could this happen due to some process on Ubuntu do you have any idea how to solve this except VPN, proxychains and shut down the router at 48h or 24h I don't know exactly how it was. By the way, to emphasize Ubuntu is 22.04
