Input IP Address Banning (Fail2Ban) 'Trusted IP Addresses' has gone missing. NGINX (111: Connection refused)

Hi,

Yesterday I noticed, 'Trusted IP Addresses' in Fail2Ban has gone missing and left only with 127.0.0.1/8.

I always had 127.0.0.1/8, ::1/128 and the server IP addresses in this section.

Also missing server IP addresses from this section caused NGINX "(111: Connection refused) while connecting to upstream" error as the Fail2Ban has recognized server IPs as 'plesk-apache-badbot'

Hope this helps someone experiencing the same.
