title: Fail2Ban unbans after 10 minutes. bantime none warning?
body: <p>having a bit of an issue with fail2ban filters, for some reason it unbans after 10 minutes even though I set the ban length to one year. Could you assist a brother out?</p>
  
  <p>jail.local declaration for filters:</p>
  
  <pre><code>[nginx-proxy]
  enabled  = true
  #port    = http,https
  action   = iptables-multiport[name=NoProxy, port="http,https"]
  filter   = nginx-proxy
  logpath  = /etc/nginx/logs/*access*.log
  bantime  = 31536000 # 1 year
  maxretry = 0
  
  [nginx-shellshock]
  enabled  = true
  #port    = http,https
  action   = iptables-multiport[name=ShellShock, port="http,https"]
  filter   = nginx-shellshock
  logpath  = /etc/nginx/logs/*access*.log
  bantime  = 31536000 # 1 year
  maxretry = 0
  </code></pre>
  
  <p>nginx-proxy.conf</p>
  
  <pre><code>[Definition]
