Hello,
fail2ban always blocks the IP addresses when a certain website is accessed.
in the failban log
2023-10-17 09:58:57,096 fail2ban.filter [1958]: INFO [plesk-apache] Found banned IP - 2023-10-17 09:58:57
Other entries cannot be found in other log files.
It only affects this WordPress website.
If I unblock the IP in fail2ban, it is blocked again after the first visit to the website.
A reinstallation via Add/Remove product components was unsuccessful.

It could be a file or directory access violation. You will be able to find out more about it in the error_log file of the affected domain.

The customer has deactivated the plugin and now it works.
