Apache error 404 when use the "back" button from browser

Hey all i dont know if im right here but i have a problem. I am using a Virutal Server with Plesk to run my Nextcloud.

Every time i use the “back” button from my Browser when im in a Folder i get some errors and my IP gets banned from my Host.

Is there something i can do this wont happen anymore. The Hosts cant turn off the IP-Bann system on single servers so i may have to fix something in my Plesk or Nextcloud settings.

thanks

Just found something out

every time i click on “recent” on the left i get the IP bann. Can i disable this button or do something it wont bann the ip?
