I have set up a droplet running on Ubuntu 18.04. Everything including my websites on WordPress is working perfectly. But as I read on many blogs regarding hardening server security, then, I tried to install Fail2Ban. Installation is successful and jail is created. But when I tried to enter the wrong password, it does not ban my IP. I have tried all tutorials below but still cannot automatically ban my IP on failed SSH login attempts. Is there somewhere I missed which makes me unable to automatically ban my IP?
Tutorial followed. https://www.digitalocean.com/community/tutorials/how-to-protect-ssh-with-fail2ban-on-ubuntu-14-04 https://www.digitalocean.com/community/tutorials/how-to-protect-an-apache-server-with-fail2ban-on-ubuntu-14-04 https://www.digitalocean.com/community/tutorials/how-to-protect-an-apache-server-with-fail2ban-on-ubuntu-14-04
Below is additional info if it helps. Webserver: Openlitespeed. Firewall: DigitalOcean Firewall & UFW. DNS: Cloudflare. SSH Connection: Putty. SSH Login: Using key pairs. SSH Password login: Disabled. Root login: Disabled.

Hi there @shahahmadyusof,
What I could suggest is to make sure you restart
fail2banafter making any configuration changes
Also make sure
findtimeisn’t set too low.
Another thing that I could suggest is to try and trigger a few unsuccessful SSH attempts from a different IP besides your main one.
Let me know how it goes! Regards, Bobby
If you want further integration between WordPress and Fail2ban you’ll need to install the Fail2ban plugin

You can install CSF in order to manage the Firewall configuration of the droplet. CSF is extremely easy to use and configure.
