If the IP of your computer is from your route, use your mobile phone to connect to Plesk (do not use the wifi connection). Enter the extension and disconnect, or find the IP and delete it.
FAQ
1.- If my IP has been blocked and I can't access Plesk, how do I resolve this?
2.- What is the BOT rule?
Enabling this rule will make the extension more sensitive to failed attempts and increase the overall level of security. If it detects patterns of malware, bots, connection bursts or robots, it will block faster.
