How to resolve “Found no accessible config files” error in fail2ban?

Fail2Ban is an intrusion prevention software framework that protects computer servers from brute-force attacks. Written in the Python programming language.

It is able to run on POSIX systems that have an interface to a packet-control system or firewall installed locally.

“Switch On” Button is either missing or it does not activate jails at Tools & Settings > IP Address Banning.

Fail2Ban is not active at Tools & Settings > Services Management.

Typically, error looks as shown below:
