Hi, we are trying to upgrade our email server. We are in the process of upgrade iRedMail from 1.1 to 1.2. We follow the documentation to implement "Fail2ban: Store banned IP addresses in SQL database" (URL: https://docs.iredmail.org/fail2ban.sql.html).

The steps are all followed: SQL DB is created and table created. The table can be updated when use the testing command to add banned IP or remove banned IP.

Now only the iRedAdmin-Pro is not working. The menu can show Activities -> Banned IP Addresses, but once clicked, it shows "Internal server error". Checked Nginx log and seems the error code is 500.

I followed the document to add below to iRedMail setting file: /var/www/iredadmin/settings.py

fail2ban_enabled = True
fail2ban_db_host = '127.0.0.1'
fail2ban_db_port = '3306'
fail2ban_db_name = 'fail2ban'
fail2ban_db_user = 'fail2ban'
fail2ban_db_password = 'xxxxxxxxxxxx'

Is that all need to do? Does this version of iRedAmin-Pro 4.3 work with fail2ban banned IP?

Thanks!
