Hi, I followed all the instructions from GitHub - centminmod/centminmod-fail2ban: fail2ban setup for centminmod.com LEMP stack with CSF Firewall

Everything appears to work properly, IP's are getting BAN and Unban however, randomly fail2ban stops working without any error.

Fail2Ban v0.10.1dev1
These are the last entries of the last shutdown:

I'm not sure how to determine why this is failing or how to debug the issue as there are no errors.

Do you have any suggestion about this issue or how I can debug it?
Thank you,
Best Regards
